Meta analysis is the process of combining and assessing the results of various studies on a particular topic in order to enhance findings.

"Meta-analysis techniques offer an organised and consistent method for examining earlier findings in the literature on a particular subject. Findings from meta-analyses may not just be quantitative but also qualitative, revealing the biases, advantages, and disadvantages of earlier investigations. The outcomes of a meta-analysis might be utilised to develop therapy suggestions or offer direction for future clinical trial design.

The ability of a meta-analysis to incorporate the findings from numerous small studies that may have lacked sufficient power to identify a statistically significant difference in an intervention's effects is what makes it so powerful. The formulation of the research topic, techniques for searching the literature, data abstraction, appropriate statistical method use, evaluation of results, assessment of publication bias, sensitivity analysis, and applicability of results are some of these areas. It is possible to assess a meta-internal analysis's validity by using a systematic method of criticism.
