Research Article vs. Review Article

What's the difference.

Research articles and review articles are both types of academic papers that are published in scholarly journals. However, they differ in terms of their purpose and content. A research article presents original research findings and is typically structured with sections such as introduction, methodology, results, and discussion. It aims to contribute new knowledge to a specific field by presenting empirical evidence and drawing conclusions. On the other hand, a review article provides a comprehensive summary and analysis of existing research on a particular topic. It synthesizes and evaluates multiple studies to provide a broader understanding of the subject matter. While research articles focus on generating new knowledge, review articles aim to provide a critical overview of the existing literature.

Further Detail

Introduction.

Research articles and review articles are two common types of scholarly publications that play a crucial role in the dissemination of scientific knowledge. While both serve the purpose of sharing information, they differ in their attributes, methodologies, and objectives. In this article, we will explore the characteristics of research articles and review articles, highlighting their similarities and differences.

Research Articles

Research articles are primary sources of scientific information that present original research findings. They are typically written by researchers or scientists who have conducted experiments, collected data, and analyzed the results. Research articles follow a specific structure, including an abstract, introduction, methodology, results, discussion, and conclusion.

In the abstract section, the authors provide a concise summary of the research question, methods, key findings, and implications. The introduction section provides background information, outlines the research problem, and states the objectives of the study. The methodology section describes the research design, sample size, data collection methods, and statistical analyses used.

The results section presents the findings of the study, often using tables, graphs, or figures to illustrate the data. The discussion section interprets the results, compares them to previous research, and discusses their implications. Finally, the conclusion section summarizes the main findings, highlights the limitations of the study, and suggests future research directions.

Research articles are typically peer-reviewed, meaning they undergo a rigorous evaluation process by experts in the field before publication. This ensures the quality and validity of the research. Research articles are essential for advancing scientific knowledge, as they contribute new insights, theories, and empirical evidence to a specific field of study.

Review Articles

Review articles, on the other hand, provide a comprehensive analysis and synthesis of existing research on a particular topic. They aim to summarize, evaluate, and critique the body of knowledge in a specific field. Review articles are often written by experts in the field who have extensive knowledge and expertise in the subject matter.

Unlike research articles, review articles do not present original research findings. Instead, they gather and analyze existing research studies, books, and other relevant sources to provide a comprehensive overview of the topic. Review articles follow a similar structure to research articles, including an abstract, introduction, body sections, and conclusion.

In the abstract section, the authors summarize the main objectives, scope, and findings of the review. The introduction section provides background information on the topic, highlights its significance, and outlines the objectives of the review. The body sections of a review article are divided into subtopics or themes, where the authors discuss and analyze the existing research in a systematic manner.

Review articles often include tables, figures, or diagrams to summarize and present the key findings from the reviewed studies. The conclusion section of a review article summarizes the main findings, identifies gaps in the existing research, and suggests future research directions.

Review articles are also typically peer-reviewed, ensuring the credibility and accuracy of the information presented. They serve as valuable resources for researchers, students, and professionals who want to gain a comprehensive understanding of a specific topic without having to read numerous individual research articles.

Similarities

While research articles and review articles have distinct characteristics, they also share some similarities. Both types of articles are published in scholarly journals and contribute to the advancement of knowledge in their respective fields. They both follow a structured format, including abstracts, introductions, and conclusions.

Additionally, both research articles and review articles undergo a peer-review process to ensure the quality and validity of the information presented. This process involves experts in the field critically evaluating the articles for their methodology, analysis, and contribution to the field.

Both research articles and review articles also require a thorough literature review to establish the context and background of the study or review. This ensures that the authors are building upon existing knowledge and addressing gaps in the field.

Differences

While there are similarities between research articles and review articles, there are also significant differences in their attributes and objectives. The most notable difference is that research articles present original research findings, while review articles analyze and synthesize existing research.

Research articles focus on addressing a specific research question or hypothesis through the collection and analysis of data. They aim to contribute new knowledge and insights to the field. In contrast, review articles aim to provide a comprehensive overview and analysis of existing research on a specific topic. They aim to summarize the current state of knowledge, identify gaps, and suggest future research directions.

Another difference is the structure of the articles. Research articles follow a specific format, including sections such as methodology, results, and discussion. Review articles also have a structured format but may vary in the number and organization of their sections, depending on the topic and the preferences of the authors.

Furthermore, the audience for research articles and review articles may differ. Research articles are often targeted towards researchers, scientists, and professionals in a specific field who are interested in the details of a particular study. Review articles, on the other hand, are valuable resources for researchers, students, and professionals who want to gain a broad understanding of a topic or need a comprehensive literature review on a specific subject.

Lastly, the time required to produce research articles and review articles may differ. Research articles often require a significant amount of time to design and conduct experiments, collect and analyze data, and write up the findings. Review articles, while still time-consuming, primarily involve extensive literature review, analysis, and synthesis of existing research.

In conclusion, research articles and review articles are two distinct types of scholarly publications that serve different purposes in the scientific community. Research articles present original research findings, contributing new knowledge to a specific field, while review articles analyze and synthesize existing research on a particular topic. Both types of articles undergo a peer-review process and follow a structured format, but their content, objectives, and target audience differ. Understanding the attributes and differences between research articles and review articles is essential for researchers, students, and professionals to effectively navigate and contribute to the scientific literature.

Review vs. Research Articles

How can you tell if you are looking at a research paper, review paper or a systematic review  examples and article characteristics are provided below to help you figure it out., research papers.

A research article describes a study that was performed by the article’s author(s). It explains the methodology of the study, such as how data was collected and analyzed, and clarifies what the results mean. Each step of the study is reported in detail so that other researchers can repeat the experiment.

To determine if a paper is a research article, examine its wording. Research articles describe actions taken by the researcher(s) during the experimental process. Look for statements like “we tested,” “I measured,” or “we investigated.” Research articles also describe the outcomes of studies. Check for phrases like “the study found” or “the results indicate.” Next, look closely at the formatting of the article. Research papers are divided into sections that occur in a particular order: abstract, introduction, methods, results, discussion, and references.

Let's take a closer look at this research paper by Bacon et al. published in the International Journal of Hypertension :

Review Papers

Review articles do not describe original research conducted by the author(s). Instead, they give an overview of a specific subject by examining previously published studies on the topic. The author searches for and selects studies on the subject and then tries to make sense of their findings. In particular, review articles look at whether the outcomes of the chosen studies are similar, and if they are not, attempt to explain the conflicting results. By interpreting the findings of previous studies, review articles are able to present the current knowledge and understanding of a specific topic.

Since review articles summarize the research on a particular topic, students should read them for background information before consulting detailed, technical research articles. Furthermore, review articles are a useful starting point for a research project because their reference lists can be used to find additional articles on the subject.

Let's take a closer look at this review paper by Bacon et al. published in Sports Medicine :

review1

Systematic Review Papers

A systematic review is a type of review article that tries to limit the occurrence of bias. Traditional, non-systematic reviews can be biased because they do not include all of the available papers on the review’s topic; only certain studies are discussed by the author. No formal process is used to decide which articles to include in the review. Consequently, unpublished articles, older papers, works in foreign languages, manuscripts published in small journals, and studies that conflict with the author’s beliefs can be overlooked or excluded. Since traditional reviews do not have to explain the techniques used to select the studies, it can be difficult to determine if the author’s bias affected the review’s findings.

Systematic reviews were developed to address the problem of bias. Unlike traditional reviews, which cover a broad topic, systematic reviews focus on a single question, such as if a particular intervention successfully treats a medical condition. Systematic reviews then track down all of the available studies that address the question, choose some to include in the review, and critique them using predetermined criteria. The studies are found, selected, and evaluated using a formal, scientific methodology in order to minimize the effect of the author’s bias. The methodology is clearly explained in the systematic review so that readers can form opinions about the quality of the review.

Let's take a closer look this systematic review paper by Vigano et al. published in Lancet Oncology :

Finding Review and Research Papers in PubMed

Many databases have special features that allow the searcher to restrict results to articles that match specific criteria. In other words, only articles of a certain type will be displayed in the search results. These “limiters” can be useful when searching for research or review articles. PubMed has a limiter for article type, which is located on the left sidebar of the search results page. This limiter can filter the search results to show only review articles.

5 Differences between a research paper and a review paper

Andrea Hayward

There are different types of scholarly literature . Some of these require researchers to conduct an original study, whereas others can be based on previously published research. Understanding each of these types and also how they differ from one another can be rather confusing for researchers, especially early career researchers. One of the most popular questions on our Q&A forum - What is the difference between a research paper and a review paper? - led us to conclude that of all the types of scholarly literature, researchers tend to be most perplexed by the distinction between a research paper and a review paper. This infographic explains the five main differences between these two types of scholarly papers.

Metrics details

Review articles are our bread and butter. Here, we would like to offer some insights on how to craft a comprehensive and authoritative assessment of a field.

Only by taking stock of where we are, can we point to where we need to go next. Review articles are designed to synthesize and critically evaluate the most important research findings within a specific field to gauge its progress and identify new research opportunities. They should be timely, objective, balanced, forward-thinking and engaging — not only informative but also easy to read. So, what does it take to craft a high-quality Review that serves as an essential resource for those interested in your field?

The first step is to determine whether your topic is timely and whether there is sufficient recent primary research to justify a crucial discussion. Start by thoroughly scanning the scientific literature to identify key findings, open questions, emerging insights, controversies and recent conclusions. A good rule of thumb is to aim for at least 30 relevant primary research papers published within the past 2–3 years. If you can meet this benchmark, it may be a good time to assess the field through a Review and start screening the broader literature. When identifying references, use a range of sources, such as literature databases and community-specific resources, and experiment with different keyword combinations to ensure comprehensive coverage. It is also beneficial to follow the work of a diverse set of researchers to get a sense of what is trending globally. Because references are the foundation of your article, make sure to cite appropriately and be mindful of inclusivity and diversity in your citations 1 .

Next, you need to find a compelling angle for your discussion. Ask yourself whether new research results have led to fresh questions or if certain areas are approaching clinical application. If not, are there emerging research directions aimed at bridging the translational gaps? Has the field shifted toward a new focus or approach? Identifying this angle will shape the narrative of your Review.

Begin by drafting a detailed outline. Identify the main topics, examples and key messages you want to convey. Organize these into a coherent storyline, drawing connections and highlighting synergies between different research areas. In addition, consider designing original illustrations that summarize the core concepts, compare different approaches and showcase key examples. Visual elements are powerful tools to enhance understanding and can help readers to grasp complex ideas quickly.

The introduction to your Review should set the stage by providing an overview of the field and context for the topic. Keep in mind that your audience may include readers who are unfamiliar with the subject, so explain mechanisms and concepts clearly and in sufficient detail. However, avoid overcomplicating things — simplicity is key. Steer clear of acronyms and abbreviations, as their meanings can vary across disciplines and may confuse readers, and keep sentences and paragraphs concise. Be sure to highlight the major advancements and knowledge gaps, emphasizing the importance and impact of the field you are reviewing.

The core of the Review — the critical discussion — should follow a logical flow. Organize the content into major sections, each dedicated to a particular area of research, with sub-sections to help to structure the discussion. Do not merely list research outcomes in chronological order; instead, compare and contrast the most representative research findings, exploring what has succeeded, what has not, and what can be learned from any failures. Look for common themes, conflicting conclusions and bottlenecks. Be as specific as possible, offering detailed information about models, systems and methodologies. To avoid ambiguity, make sure it is clear whether you are discussing established findings or proposing hypotheses. Incorporate tables to compare systems, metrics or approaches — such as clinical trials, performance outcomes or device designs — and consider adding text boxes for technical details that support the main discussion.

Conclude your Review with an outlook section that summarizes the key take-home messages and highlights future directions for the field, pinpointing specific actionable milestones. By the end, readers should have a clear understanding of the current state of the field, its future challenges, and the steps needed to overcome them from both engineering and translational perspectives. Ideally, the reader is left with many ideas for new experiments and collaborations.

Finally, choose a title that is clear, descriptive and concise, avoiding vague terms, such as ‘advances’, ‘emerging’ or ‘recent’, to make your Review easy to find and classify. The title should include key terms that reflect the content of the Review. Similarly, the abstract should be succinct, providing a snapshot of the article by briefly introducing the field and outlining the major themes of your article. Think of it as a miniature version of the Review.

“A good Review should always teach you something new — even if you have been in the field for a long time.”

A good Review should always teach you something new — even if you have been in the field for a long time. Writing a Review article offers a unique opportunity to reflect on a field and deepen your understanding of core concepts. The process might even lead you to fresh insights of your own.

Research Articles and Review Articles Defined Review

"A  research article  is a  primary source ...that is, it  reports the methods and results of an original study performed by the authors . The kind of study may vary (it could have been an experiment, survey, interview, etc.), but in all cases, raw data have been collected and analyzed by the authors, and conclusions drawn from the results of that analysis.

A  review article  is a  secondary source ...it is written about other articles, and does not report original research of its own.  Review articles are very important, as they draw upon the articles that they review to suggest new research directions, to strengthen support for existing theories and/or identify patterns among existing research studies.   For student researchers, review articles provide a great overview of the existing literature on a topic.    If you find a literature review that fits your topic, take a look at its references/works cited list for leads on other relevant articles and books!"

Difference between Reviews and Research Articles

Review Article: Identifies previously published research on a topic and summarizes the information (secondary source). Discusses what is already known and can be used to identify gaps in the field.  Usually no set layout. No original research is being presented. Written for a more general audience and easier to read. Both Written by a subject expert such as a scientist or researcher. Can be published in a scholarly, peer-reviewed journal. Research Article: Follows the scientific method. Usually provides a brief background on prior research (introduction) Conducts an experiment and reports the findings. Authors have NEW original research data (primary source) and discusses their results. Written at an advanced level; usually contains lots of jargon.

Research Article Break Down Review

Research articles follow a particular format.  Look for:

  • A brief  introduction  will often include a review of the existing literature on the topic studied, and explain the rationale of the author's study.
  • A  methods  section, where authors describe how they collected and analyzed data.  Statistical analysis are included.  
  • A  results  section describes the outcomes of the data analysis.  Charts and graphs illustrating the results are typically included.
  • In the  discussion , authors will explain their interpretation of their results and theorize on their importance to existing and future research.
  • References  or  works cited  are always included.  These are the articles and books that the authors drew upon to plan their study and to support their discussion.

What Is The Difference Between A Scholarly Research Article And A Review Article?

If you are new in the academic world, you may find the types of academic articles dizziying. The more common ones include research articles, and also review articles. How are they similar and different from each other? Distinguishing between research and review articles is crucial. 

In this post, let’s explore what research and review articles are, and how are they different.

Research Article vs. Review Article

What is a research article .

A research article serves as the cornerstone of the academic and scientific community, standing as a detailed report on original findings.

Unlike review articles which synthesise existing literature to provide an overview, research articles present primary research with fresh data, exploring uncharted territories within a specific field.

research and review article

The devil is in the details when it comes to these scholarly works. Original studies not only pose a research question but delve into methodologies that range from complex experimental designs to detailed observations.

Scholarly articles are often peer-reviewed, meaning that other experts in the field scrutinise the work before publication to ensure its validity and contribution to the field.

The empirical nature of research articles means that the raw data and analysis methods are laid bare for replication—a fundamental tenet of scientific inquiry. These papers typically include:

  • Introduction: Introduces the problem
  • Methodology: T he means by which the study was conducted
  • Results: F indings from the study
  • Discussion: Connects the findings to the bigger picture, highlighting implications and potential for future research.

While some journals accept such articles readily, the journey of a paper from research question to published research is fraught with meticulous data collection and rigorous peer evaluation.

For the keen observer, it’s the systematic reviews and meta-analyses that truly offer a glimpse into the current state of understanding, weaving through the tapestry of existing knowledge to pinpoint gaps and suggest paths forward.

It’s this level of detail—often hidden in plain sight in methods and results—that serves as a rich vein of information for those looking to conduct systematic reviews or embark on a similar empirical journey.

Whether it’s a clinical case study or a large-scale trial, the research article is an essential treasure in the scholarly literature, serving as a building block for academic writing and future exploration.

What Is A Review Article?

A review article stands out in the scholarly world as a synthesis of existing research, providing a critical and comprehensive analysis of a particular topic.

Unlike original research articles that report new empirical findings, review articles serve as a bridge connecting a myriad of studies, offering an overview that discerns patterns, strengths, and gaps within published work.

research and review article

Peer-reviewed and systematically organised, these articles are essential for scholars who wish to familiarise themselves with the current state of knowledge on a given subject without having to delve into each individual research paper.

Insiders know that the crafting of a review article is an art in itself. Authors meticulously collect and analyse data from various sources, often employing methods like meta-analysis or systematic review searches to compare and combine findings.

They don’t just summarise existing literature; they synthesise it, providing new insights or revealing unexplored areas that could benefit from future research. It’s a rigorous process, often involving the intricate task of:

  • Comparing clinical trials,
  • Conducting extensive literature reviews, or even
  • Generating new frameworks for understanding complex academic concepts.

The value of a well-conducted review is immense. Journals publishing these articles often see them as keystones, providing a foundation upon which other researchers can build.

Such reviews can point to the need for new primary research, challenge existing paradigms, or even sometimes shift the direction of scholarly inquiry.

For the discerning academic, a review article is not just a summary—it’s a roadmap for what comes next in the quest for knowledge.

How Are Review And Research Articles Different?

In the scholarly cosmos, the distinction between a research article and a review article is fundamental, yet it’s a source of perplexity for budding academics. Diving into the anatomy of these articles reveals their distinct roles in academia.

Original Research vs Synthesised Knowledge

A research article is an original study, presenting novel findings. It follows a stringent structure: an abstract to summarize the study, an introduction to set the stage, followed by methods, results, and a discussion that connects the findings to broader implications.

A review article instead synthesises the information from one or many of these original studies, into an article to allow easier reading. Some also offer additional insights for the readers. 

Anatomy & Structure

An original research article is usually brimming with original data, charts, and perhaps phrases like “we investigated” or “the study found,” signifying fresh empirical insights. At the most basic, a research article usually contains sections such as:

  • Introduction
  • Methodology
  • Future research ideas

A review article usually begins with an abstract summarising the scope and findings of the review. The main body is divided into sections that often include:

  • An introduction to the topic
  • A discussion segment that synthesises and analyses the compiled research
  • Subtopics that further categorise the research by themes or methodologies. 

Finally, it concludes with a summary or conclusion that reflects on the current state of research, identifies gaps, and may suggest directions for future studies, accompanied by a thorough list of references.

A research article is written to share new findings and original data on a particular research. This means the information are fresh, and new to the scientific community.

An example title of a research article may be “Investigating Necrotic Enteritis in 15 Californian Broiler Chicken Farms.”

A review article is more akin to an academic digest, offering a synthesis of existing research on a topic. It typically lacks the methodology and results sections found in research papers.

The main goal is to give a panoramic view of the existing literature, gaps, and sometimes, a meta-analysis combining findings from various studies to distill a more substantial conclusion.

An example of a review article about Necrotic Enteritis may be something like this: “Necrotic Enteritis in Broiler Chickens – What We Know So Far.” 

Impact and Use in Academia

Research articles are the primary sources, documenting original work from scientists, as they conduct researches in their fields.

research and review article

Original research articles are crucial in academia as they contribute new knowledge, support evidence-based advancements, and form the foundation for subsequent scholarly inquiry.

Research articles: 

  • Provide detailed methodology and results for peer scrutiny
  • Foster academic dialogue,
  • Often the preferred source for cutting-edge information in a given field, and
  • Directly impacting teaching, policy-making, and further research.
Review articles are summaries that distill wisdom from multiple sources to shed light on the current state of knowledge, often guiding future research.

They are usually seen as secondary sources, containing insights that research articles might not individually convey.
