What is a systematic review with meta-analysis?
A systematic review attempts to gather all available empirical research by using clearly defined, systematic methods to obtain answers to a specific question. A meta-analysis is the statistical process of analyzing and combining results from several similar studies.
How do you write a meta-analysis for a literature review?
Here’s the process flow usually followed in a typical systematic review/meta-analysis:
- Develop a research question.
- Define inclusion and exclusion criteria.
- Locate studies.
- Select studies.
- Assess study quality.
- Extract data.
- Conduct a critical appraisal of the selected studies.
- Step 8: Synthesize data.

8 Stages of a Systematic Review and Meta Analysis
- Formulate the review question.
- Define inclusion and exclusion criteria.
- Develop search strategy and locate studies.
- Select studies.
- Extract data.
- Assess study quality.
- Analyze and interpret results.
- Disseminate findings.
What is an example of meta-analysis?
For example, a systematic review will focus specifically on the relationship between cervical cancer and long-term use of oral contraceptives, while a narrative review may be about cervical cancer. Meta-analyses are quantitative and more rigorous than both types of reviews.
How do you know if it’s a meta-analysis?
Conduct a thorough search of the literature. Screen your search results against your pre-specified selection criteria to identify included studies. Appraise the quality of studies found. Synthesise the evidence, this is where meta-analysis may or may not come in.
What is the difference between a literature review and a meta-analysis?
A Literature review is the analysis of all existing literature in a field of study. Meta Analysis, on the other hand, is an analysis of similar scientific studies to establish an estimate closest to the common point of truth that exist between them.
What should a meta-analysis include?
The steps of meta analysis are similar to that of a systematic review and include framing of a question, searching of literature, abstraction of data from individual studies, and framing of summary estimates and examination of publication bias.
What kind of study is a meta-analysis?
Meta-analysis is a quantitative, formal, epidemiological study design used to systematically assess the results of previous research to derive conclusions about that body of research. Typically, but not necessarily, the study is based on randomized, controlled clinical trials.
What are the advantages of a meta-analysis?
Meta-analysis provides a more precise estimate of the effect size and increases the generalizability of the results of individual studies. Therefore, it may enable the resolution of conflicts between studies, and yield conclusive results when individual studies are inconclusive.
How are systematic reviews and meta-analyses used in research?
Evaluating systematic reviews and meta-analyses Systematic review and meta-analysis procedures make use of explicit methods to methodically search and critically appraise and synthesize the medical care research literature. The methods involve refining a clinical question, designing a search procedure to find eligible studies, and determining the …
How is a scoping review different from a meta-analysis?
META-ANALYSIS. A scoping review is a preliminary investigation that clarifies the range and nature of the evidence base, using flexible procedures. Such scoping reviews can suggest strategies for a full systematic review and can also indicate whether statistical integration (a meta-analysis) is feasible.
Which is the best definition of a meta-analysis?
A meta-analysis is a valid, objective, and scientific method of analyzing and combining different results. Usually, in order to obtain more reliable results, a meta-analysis is mainly conducted on randomized controlled trials (RCTs), which have a high level of evidence [2] (Fig. 1).
How to assess the validity of a systematic review?
Then assess the validity of the systematic review, which is reflected by quality of the individual studies, the rigor with which the systematic methods were applied, and the extent of heterogeneity. If the results of the systematic review are valid, then is the effect important enough to make a difference in your clinical practice?
