Glass and Smith’s meta-analysis on class size covered 77 studies and nearly 725 separate comparisons. -4 third contribution was the demonstration that the influence of dozens of study features might be explored in reviews. Although meta-analysis is widely used in epidemiology and evidence-based medicine today, a meta-analysis of a medical treatment was not published until 1955. In the 1970s, more sophisticated analytical techniques were introduced in educational research , starting with the work of Gene V. Glass , Frank L. Schmidt and John E. Hunter .

n. The process or technique of synthesizing research results by using various statistical methods to retrieve, select, and combine results from previous interpreting a meta-analysis is an impor-tant skill for physical therapists. The pur-pose of this commentary is to expand on existing articles describing meta-analysis interpretation,6,13,14,42,61 discuss differences in the results of a meta-analysis based on the treatment questions, explore special cases in the use of meta-analysis, and Se hela listan på frontiersin.org 4.2 Random-Effects-Model. Previously, we showed how to perform a fixed-effect-model meta-analysis using the metagen and metacont functions.. However, we can only use the fixed-effect-model when we can assume that all included studies come from the same population.

Instead of basing conclusions on a single study, a meta-analysis looks at numerous studies for the answer.

These systematic reviews integrate and synthesize existing research studies in an attempt to derive new information by quantitative statistical analysis. Meta-analyysin modernina isänä voidaan pitää Karl Pearsonia, joka yhdisti jo vuonna 1904 julkaisussaan useiden julkaisujen tuloksia..
