Abstract
Jones et al. (April 23 issue)1 discount the possibility that the selection of patients was a factor in the negative outcome of the Surgical Treatment for Ischemic Heart Failure (STICH) trial (ClinicalTrials.gov number, NCT00023595). Their argument, however, would be much strengthened by providing information on the clinical profile and number of patients who were eligible for the trial but were not enrolled. Such information is sorely needed to determine the generalizability of the findings of a trial in which the yearly recruitment averaged only three patients per site.
