To the Editor: Dr Bennett-Guerrero and colleagues1 reported results from a multicenter randomized controlled trial of the effect of an implantable gentamicin-collagen sponge on sternal wound infections after cardiac surgery. No effect was seen in the total number of sternal wound infections. The small differences in the numbers of deep infections and surgically treated infections did not reach statistical significance.
