Results

Eight patients (5%, 95% CI 2-9%) had surgical-site infections in the intraoperative group compared with 16 (9%, 5-14) in the extended group. The relative risk of surgical-site infections with intraoperative antimicrobial prophylaxis was 0.51 (0.22-1.16), which revealed statistically significant non-inferiority (p<0.0001).
