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.
1. Purpose and Scope
To help you develop a literature review, gather information on existing research, sub-topics, relevant research, and overlaps. Note initial thoughts on the topic - a mind map or list might be helpful - and avoid unfocused reading, collecting irrelevant content. A literature review serves to place your research within the context of existing knowledge. It demonstrates your understanding of the field and identifies gaps that your research aims to fill. This helps in justifying the relevance and necessity of your study.
To avoid over-reading, set a target word count for each section and limit reading time. Plan backwards from the deadline and move on to other parts of the investigation. Read major texts and explore up-to-date research. Check reference lists and citation indexes for common standard texts. Be guided by research questions and refocus on your topic when needed. Stop reading if you find similar viewpoints or if you're going off topic.
You can use a "Synthesis Matrix" to keep track of your reading notes. This concept map helps you to provide a summary of the literature and its connections is produced as a result of this study. Utilizing referencing software like RefWorks to obtain citations, you can construct the framework for composing your literature evaluation.
2. Source Selection
Focus on searching for academically authoritative texts such as academic books, journals, research reports, and government publications. These sources are critical for ensuring the credibility and reliability of your review.
3. Thematic Analysis
Instead of merely summarizing sources, identify and discuss key themes that emerge from the literature. This involves interpreting and evaluating how different authors have tackled similar issues and how their findings relate to your research.
4. Critical Evaluation
Adopt a critical attitude towards the sources you review. Scrutinize, question, and dissect the material to ensure that your review is not just descriptive but analytical. This helps in highlighting the significance of various sources and their relevance to your research.
Each work's critical assessment should take into account:
Provenance: What qualifications does the author have? Are the author's claims backed up by proof, such as first-hand accounts from history, case studies, stories, statistics, and current scientific discoveries? Methodology: Were the strategies employed to locate, collect, and evaluate the data suitable for tackling the study question? Was the sample size suitable? Were the findings properly reported and interpreted? Objectivity : Is the author's viewpoint impartial or biased? Does the author's thesis get supported by evidence that refutes it, or does it ignore certain important facts? Persuasiveness: Which of the author's arguments is the strongest or weakest in terms of persuasiveness? Value: Are the author's claims and deductions believable? Does the study ultimately advance our understanding of the issue in any meaningful way?
5. Categorization
Organize your literature review by grouping sources into categories based on themes, relevance to research questions, theoretical paradigms, or chronology. This helps in presenting your findings in a structured manner.
6. Source Validity
Ensure that the sources you include are valid and reliable. Classic texts may retain their authority over time, but for fields that evolve rapidly, prioritize the most recent research. Always check the credibility of the authors and the impact of their work in the field.
7. Synthesis and Findings
Synthesize the information from various sources to draw conclusions about the current state of knowledge. Identify trends, controversies, and gaps in the literature. Relate your findings to your research questions and suggest future directions for research.
