Then, what is a meta analysis and why is it useful?
Meta-analysis is the statistical procedure for combining data from multiple studies. When the treatment effect (or effect size) is consistent from one study to the next, meta-analysis can be used to identify this common effect.
Additionally, is meta analysis reliable? 1. A meta-analysis is a safer starting point than a single study – but it won't necessarily be more reliable. A meta-analysis is usually part of a systematic review. A bad or patchy meta-analysis might not come to as reliable conclusions as a well-conducted, adequately powered single study.
Beside above, what are the advantages of meta analysis?
(a) Results of meta-analyses can provide better estimates of the relation in the population than single studies. (b) The precision and validity of estimates can be improved as more data are used in a meta-analysis, and the increased amount of data increases the statistical power to detect an effect.
What is meta analysis review?
Meta-analysis is a systematic review of a focused topic in the literature that provides a quantitative estimate for the effect of a treatment intervention or exposure. The results of a meta-analysis can be used to form treatment recommendations or to provide guidance in the design of future clinical trials.
