Meta-analysis is an analytical tool that permits the evaluation of a diagnostic or therapeutic modality through the appropriate use of previously published smaller studies. 21 Meta-analysis is not the simple pooling of data reported in numerous small studies, a notion that has often caused investigational errors.

1. A Meta-Analysis pools together the populations from different studies, such as Randomized Controlled Trials, into one statistical analysis and treats them as one large study population with one conclusion. a) True b) False. 2. One potential design pitfall of Meta-Analyses that is important to pay attention to is: a) Whether it is evidence-based.

the meta-analysis. The selection criteria will depend on the purpose of the meta-analysis, but it is always necessary to specify the types of study designs that will be accepted (e.g., only experimental designs, or also quasi-experimental ones, etc.). For example, in the meta-analysis on OCD

HOW TO APPROACH A META-ANALYSIS Dr Julie Cox, Consultant Radiologist, University Hospital of North Durham Introduction Although there has always been some controversy about its validity, meta-analysis has become popular as the number of studies with similar protocols has grown. By

Sensitivity Analysis. To determine if the results of the two main analyses would change if one study was removed, we conducted sensitivity analyses using the Comprehensive Meta-Analysis software.

First, "classic" meta-analysis applies liberal inclusion criteria. Glass argued that one should not disregard studies on the basis of study quality a priori; a meta-analysis itself can determine if study quality is related to variance in reported treatment effect. Second, the unit of analysis is the study finding.

The present study had several strengths. All studies included in this meta-analysis were of a prospective design, which eliminates the possibility of recall and selection biases. We have acknowledged.

Therefore, to evaluate these associations and summarize available observational evidence, we attempted to conduct a meta-analysis of prospective studies on this topic. Figure 1: Flow diagram for.
