Interesting re-analysis of data from 4 clinical trials to determine if the presence and type of stenosis at baseline impacts ability to achieve clinical and endocopic outcomes. However, main analyses appear to compare outcomes among patients without non-passable stenosis at baseline to those with non-passable stenosis, without accounting for other demographic and clinical variables that may be associated with clinical and endocopic outcomes. Analyses could be strengthened by risk-adjusting for important covariates.
