Question

Quizplus · Accepted Answer

A meta-analysis typically involves a quantitative combination of results from several studies to provide a more reliable estimate of the effects of a particular intervention or treatment. This involves statistical analysis of data from the studies, rather than simply summarizing or describing them. A narrative review (A) may also summarize several articles, but may not necessarily use pre-set criteria or involve statistical analysis. B and D can also be included in a meta-analysis, but are not the primary focus.
