"A systematic review is a summary of evidence, typically conducted by an expert or expert panel on a particular topic, that uses a rigorous process (to minimize bias) for identifying, appraising, and synthesizing studies to answer a specific clinical question and draw conclusions about the data gathered."

"A meta-analysis is a statistical procedure that integrates the results of several independent studies" and focuses on contrasting and comparing results from different studies to identify consistent patterns and discrepancies amongst the results.
