Meta-analysis is the rubric used to describe quantitative methods for combining evidence across studies. Because meta-analysis usually relies on data in the form of summary statistics derived from the primary analyses of studies, it is truly an analysis of the results of Statistical methodology in meta-analysis book :// Genre/Form: Statistics: Additional Physical Format: Online version: Hedges, Larry V.

Statistical methodology in meta-analysis. Princeton, N.J.: ERIC Clearinghouse on Meta-analysis has become an important supplement to traditional methods of research reviewing, although many problems must be addressed by the reviewer who carries out a meta-analysis.

These problems include identifying and obtaining appropriate studies, extracting estimates of effect size Statistical methodology in meta-analysis book the studies, coding or classifying studies, analyzing the data, and reporting the results of the ?id=ED   Operationally meta-analysis is a quantitative technique that uses specific steps (for example, effect sizes) to show the strength of variable relationships for studies included in the analysis   This book was the first source to compile the results from a scattered literature into a systematic treatment of the classical statistical approach to meta-analysis.

Meta-analyses can widely differ with regard to their methodological and analytical aspects.

The first relevant difference concerns the statistical framework used to conduct the analysis. For example, a frequentist or Bayesian approach can be employed for pooling the data [1, 2]. Data modelling on a Meta-Analysis is the quantitative integration of research findings with the help of statistical tools.

In this paper we aim to make the methodology accessible to non-statisticians by presenting and explaining a series of Meta-analysis combines results from several independent studies.

Different methods are available to carry out meta-analyses for binary and continuous outcomes. The effect measures used for binary outcomes are odds ratio (OR), relative risk (RR), risk difference (RD), arcsine difference (AS), hazard ratio (HR) etc.
