The aim of the PRISMA statement is to help authors improve the reporting of systematic reviews and meta-analyses. [3] PRISMA has mainly focused on systematic reviews and meta-analysis of randomized trials, but it can also be used as a basis for reporting reviews of other types of research (e.g., diagnostic studies, observational studies).
An example forest plot of five odds ratios (squares, proportional to weights used in meta-analysis), with the summary measure (centre line of diamond) and associated confidence intervals (lateral tips of diamond), and solid vertical line of no effect. Names of (fictional) studies are shown on the left, odds ratios and confidence intervals on ...
The social science research community was concerned that the condemnation by government legislatures might have a chilling effect on the future publication of controversial research results. The study's lead author is the psychologist Bruce Rind; it expanded on a 1997 meta-analysis for which Rind is also the lead author. [2]
A meta-analysis of such expression profiles was performed to derive novel conclusions and to validate the known findings. [148] Meta-analysis of whole genome sequencing studies provides an attractive solution to the problem of collecting large sample sizes for discovering rare variants associated with complex phenotypes.
For example, evidence-based medicine is increasingly reliant on meta-analysis to assess evidence. Conceptual illustration of how publication bias affects effect estimates in a meta-analysis. When negative effects are not published, the overall effect estimate tends to be inflated. From Nilsonne (2023). [28]
A meta-regression can be classified in the same way—meta-regression and network meta-regression—depending on the number of distinct treatments in the regression analysis. Meta-analysis (and meta-regression) is often placed at the top of the evidence hierarchy provided that the analysis consists of individual participant data of randomized ...
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. [1] A systematic review extracts and interprets data from published studies on the topic (in the scientific literature), then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based ...
For example, if both p-values are around 0.10, or if one is around 0.04 and one is around 0.25, the meta-analysis p-value is around 0.05. In statistics , Fisher's method , [ 1 ] [ 2 ] also known as Fisher's combined probability test , is a technique for data fusion or " meta-analysis " (analysis of analyses).
