This revised data request addresses a number of the questions raised after the first review of the proposal. However, it is still unclear whether the requested trials will fulfill the eligibility criteria. The investigators note that the trials must have missing not at random as part of the design, with a substantial porpotion of drop-out. It seems as if the investigators could have reviewed some of the trial specific information regarding drop-out (e.g. ClinicalTrials.gov or the corresponding publications) to determine potential eligibility. That being said, if the investigators are able to identify an eligible trial, this work has the potential address a gap in the statistical literature.
