- ekianjo 10y agoNo, you don't need to do meta-analysis. Without combining the results of multiple trials together, you can see if an observed effect in one trial is found in other trials through independent analysis.

The purpose of meta-analysis goes beyond pooling. Indeed, one of the first steps in meta-analysis is "Is pooling even a good idea?"
