Hardin et al ask about the baseline of wound infection in the power analysis. In previous clinical studies, the rate of wound infection has been 9%.3 Randomizing patients to closure with either a short or a long stitch, we expected a higher rate of infection with a long stitch. As we estimated the rate to be 12% with a long stitch and 6% with a short stitch, a power of 80% was achieved with 352 patients in each study group.
