Dabigatran versus enoxaparin after total hip replacement – Authors’ reply

Christoph Pechlaner and Peter Marschang highlight the use of aspirin and graduated compression stockings in our trial. The efficacy benefit of aspirin in patients undergoing hip replacement surgery has not been shown. Specifically, in the Pulmonary Embolism Prevention trial,

patients who underwent hip replacement and received aspirin showed no significant efficacy benefit over placebo. In our trial, the use of aspirin and compression stockings was similar in the three treatment groups (table), with no significant difference in any efficacy or safety outcome among patients using either therapy alone or in combination.
