Document Summary
Research integration and synthesis: the systematic and rigorous integration and synthesis of evidence is a cornerstone of. Meta-analysis: advantages: objectivity statistical integration eliminates bias in drawing conclusions when results in different studies are at odds. Increased power reduces the risk of a type ii error compared to a single study: despite these advantages, meta-analysis is not always appropriate. Indiscriminate use has led critics to warn against potential abuses. Criteria for using meta-analysis in systematic review: must decide whether statistical integration is suitable, research question or hypothesis should be essentially identical across studies.

An advantage of meta-analysis is that it reduces the risk of a type i error as compared to a single study: true, false.
