Imputing Variance Estimates

Good Afternoon All,I am writing a protocol for a meta-analysis and was asked by the funder to include our plan for handling studies that provide data on a condinuous outcome (change from baseline) but no measure of variance.

I was interested if anyone had experience with this and could offer any advice. ThanksBill William L. Baker, Pharm.D., FCCP, BCPS (AQ…See More
