NOTE. Data are no. (%) or proportion (%) of surgical procedures, unless otherwise indicated. Data were not available on all surgical procedures.
a
For pairwise comparison with chlorhexidine.
b
Of the 182 SSIs in the study, 4 involved surgical procedures that did not use any of the defined preparation solutions, so the total here is 178.
