We found no additional trials, but we were able to obtain unpublished data from three trials that were not included in the original review. The trials were not included in the original review because the participants in the trials as a whole did not meet our inclusion criteria. However, the trials each contained a subgroup of patients that did meet our inclusion criteria. We were also able to obtain additional unpublished data from some of the originally included trials.
