I wish to comment on the article by Margolis and colleagues.1 The term risk factors used by the authors to describe a poor response to compression therapy is confusing because an increase in wound area or wound duration cannot be considered a risk factor per se, but rather a consequence or clinical evidence of chronic venous insufficiency. Surprisingly, other indicators of poor response to compression therapy such as reflux in the deep venous system or incompetent perforating veins were not evaluated in this study.2
