- Meta-Analysis
-
Definition: A way of combining data from many different research studies. A meta-analysis is a statistical process that combines the findings from individual studies.
Example: For example, researchers wanted to know about the risk of stomach bleeding in people taking aspirin. They did a meta-analysis of data from 24 clinical trials with nearly 66,000 participants and found that the risk of stomach bleeding was 2.47 percent with aspirin compared to 1.42 percent with placebo (inactive substance).
