Specifies the number of studies evaluated orselected
Steps, and targets of constructing a good review article are listed in Table 3 . To write a good review article the items in Table 3 should be implemented step by step. [ 11 – 13 ]
Steps of a systematic review
Formulation of researchable questions | Select answerable questions |
Disclosure of studies | Databases, and key words |
Evaluation of its quality | Quality criteria during selection of studies |
Synthesis | Methods interpretation, and synthesis of outcomes |
It might be helpful to divide the research question into components. The most prevalently used format for questions related to the treatment is PICO (P - Patient, Problem or Population; I-Intervention; C-appropriate Comparisons, and O-Outcome measures) procedure. For example In female patients (P) with stress urinary incontinence, comparisons (C) between transobturator, and retropubic midurethral tension-free band surgery (I) as for patients’ satisfaction (O).
In a systematic review on a focused question, methods of investigation used should be clearly specified.
Ideally, research methods, investigated databases, and key words should be described in the final report. Different databases are used dependent on the topic analyzed. In most of the clinical topics, Medline should be surveyed. However searching through Embase and CINAHL can be also appropriate.
While determining appropriate terms for surveying, PICO elements of the issue to be sought may guide the process. Since in general we are interested in more than one outcome, P, and I can be key elements. In this case we should think about synonyms of P, and I elements, and combine them with a conjunction AND.
One method which might alleviate the workload of surveying process is “methodological filter” which aims to find the best investigation method for each research question. A good example of this method can be found in PubMed interface of Medline. The Clinical Queries tool offers empirically developed filters for five different inquiries as guidelines for etiology, diagnosis, treatment, prognosis or clinical prediction.
As an indispensable component of the review process is to discriminate good, and bad quality researches from each other, and the outcomes should be based on better qualified researches, as far as possible. To achieve this goal you should know the best possible evidence for each type of question The first component of the quality is its general planning/design of the study. General planning/design of a cohort study, a case series or normal study demonstrates variations.
A hierarchy of evidence for different research questions is presented in Table 4 . However this hierarchy is only a first step. After you find good quality research articles, you won’t need to read all the rest of other articles which saves you tons of time. [ 14 ]
Determination of levels of evidence based on the type of the research question
I | Systematic review of Level II studies | Systematic review of Level II studies | Systematic review of Level II studies | Systematic review of Level II studies |
II | Randomized controlled study | Crross-sectional study in consecutive patients | Initial cohort study | Prospective cohort study |
III | One of the following: Non-randomized experimental study (ie. controlled pre-, and post-test intervention study) Comparative studies with concurrent control groups (observational study) (ie. cohort study, case-control study) | One of the following: Cross-sectional study in non-consecutive case series; diagnostic case-control study | One of the following: Untreated control group patients in a randomized controlled study, integrated cohort study | One of the following: Retrospective cohort study, case-control study (Note: these are most prevalently used types of etiological studies; for other alternatives, and interventional studies see Level III |
IV | Case series | Case series | Case series or cohort studies with patients at different stages of their disease states |
Rarely all researches arrive at the same conclusion. In this case a solution should be found. However it is risky to make a decision based on the votes of absolute majority. Indeed, a well-performed large scale study, and a weakly designed one are weighed on the same scale. Therefore, ideally a meta-analysis should be performed to solve apparent differences. Ideally, first of all, one should be focused on the largest, and higher quality study, then other studies should be compared with this basic study.
In conclusion, during writing process of a review article, the procedures to be achieved can be indicated as follows: 1) Get rid of fixed ideas, and obsessions from your head, and view the subject from a large perspective. 2) Research articles in the literature should be approached with a methodological, and critical attitude and 3) finally data should be explained in an attractive way.
Learn how to write a review article.
What is a review article? A review article can also be called a literature review, or a review of literature. It is a survey of previously published research on a topic. It should give an overview of current thinking on the topic. And, unlike an original research article, it will not present new experimental results.
Writing a review of literature is to provide a critical evaluation of the data available from existing studies. Review articles can identify potential research areas to explore next, and sometimes they will draw new conclusions from the existing data.
To provide a comprehensive foundation on a topic.
To explain the current state of knowledge.
To identify gaps in existing studies for potential future research.
To highlight the main methodologies and research techniques.
There are some journals that only publish review articles, and others that do not accept them.
Make sure you check the aims and scope of the journal you’d like to publish in to find out if it’s the right place for your review article.
Below are 8 key items to consider when you begin writing your review article.
Make sure you have read the aims and scope for the journal you are submitting to and follow them closely. Different journals accept different types of articles and not all will accept review articles, so it’s important to check this before you start writing.
Define the scope of your review article and the research question you’ll be answering, making sure your article contributes something new to the field.
As award-winning author Angus Crake told us, you’ll also need to “define the scope of your review so that it is manageable, not too large or small; it may be necessary to focus on recent advances if the field is well established.”
When finding sources to evaluate, Angus Crake says it’s critical that you “use multiple search engines/databases so you don’t miss any important ones.”
For finding studies for a systematic review in medical sciences, read advice from NCBI .
Spend time writing an effective title, abstract and keywords. This will help maximize the visibility of your article online, making sure the right readers find your research. Your title and abstract should be clear, concise, accurate, and informative.
For more information and guidance on getting these right, read our guide to writing a good abstract and title and our researcher’s guide to search engine optimization .
Does a literature review need an introduction? Yes, always start with an overview of the topic and give some context, explaining why a review of the topic is necessary. Gather research to inform your introduction and make it broad enough to reach out to a large audience of non-specialists. This will help maximize its wider relevance and impact.
Don’t make your introduction too long. Divide the review into sections of a suitable length to allow key points to be identified more easily.
Make sure you present a critical discussion, not just a descriptive summary of the topic. If there is contradictory research in your area of focus, make sure to include an element of debate and present both sides of the argument. You can also use your review paper to resolve conflict between contradictory studies.
Angus Crake, researcher
As part of your conclusion, include making suggestions for future research on the topic. Focus on the goal to communicate what you understood and what unknowns still remains.
Always perform a final spell and grammar check of your article before submission.
You may want to ask a critical friend or colleague to give their feedback before you submit. If English is not your first language, think about using a language-polishing service.

Article Review Example "While the article presents compelling evidence linking social media usage to mental health issues, it is important to acknowledge some limitations in Smith's study. The sample size of the research was relatively small. It comprises only 100 participants, which may limit the generalizability of the findings.
To write an article review effectively, start by thoroughly reading the article and taking detailed notes. Consider the author's purpose in writing the article. Summarize the key points, and critically evaluate the article by assessing its accuracy, strengths, and weaknesses. Then, outline your thoughts, develop a thesis, and compose your review.
Article review format. The formatting of an article review will always come down to what type of assignment you plan to write and your citation style. Still, you should provide a title page, the course title, your name, and the work date. In certain cases, it may be required to include an abstract of 200 to 300 words.
A review article is a type of professional essay writing. So you need to study its subject carefully. Use multiple sources and highlight the main arguments. Then form your own opinion on the given topic. In conclusion of your article review, you should bring new arguments for or against the author's opinion.
Example. Following, we have an example of a summary and an evaluation of a research article. Note that in most literature review contexts, the summary and evaluation would be much shorter. This extended example shows the different ways a student can critique and write about an article. Citation. Chik, A. (2012).

Your review might be guided by the following questions:
Summaries and critiques are two ways to write a review of a scientific journal article. Both types of writing ask you first to read and understand an article from the primary literature about your topic. The summary involves briefly but accurately stating the key points of the article for a reader who has not read the original article.
In comparison, a book review article example could be critiqued by a fellow author or even a student in the chosen field. Depending on the critique criteria and the work being reviewed, there could also be certain points asked for addition which should be checked and noted by the lecturer or supervisor. Otherwise, follow the article review ...
