Combining evidence from multiple electronic health care databases: Performances of one-stage and two-stage meta-analysis in matched case-control studies In the article, “Combining evidence from multiple electronic health care databases: performances of one-stage and two-stage meta-analysis in matched case-control studies,” the author would like to correct the last bulleted sentence in Keypoints section: “One-stage meta-analysis may be preferred over two-stage meta-analysis when analysis in separate datasets is infeasible due to scarce data.” The authors apologize for any misunderstanding this may have caused.
