Methods of synthesis of data for meta-analyses

Studies included in the statistical analysis must cover the same question and contain data that is comparable.
The results of a meta-analysis are most frequently represented in a Forest plot.
See the Guidelines section of this guide for more details about the statistical methods used for meta-analysis and how to use them.

Effect size calculator
This is a web-based effect-size calculator. It is designed to facilitate the computation of effect-sizes for meta-analysis. Four effect-size types can be computed from various input data: the standardized mean difference, the correlation coefficient, the odds-ratio, and the risk-ratio.
RevMan facilitates preparation of protocols and full reviews, including text, characteristics of studies, comparison tables, and study data. It can perform meta-analysis of the data entered, and present the results graphically.
