Intraoperative surgical site infection control and prevention: a position paper and future addendum to WSES intra-abdominal infections guidelines.

Data showed also a nonsignificant trend toward greater protective effect in studies using a dual-ring protector (RR = 0.31, 95% CI 0.14–0.67, P = 0.003), rather than a single-ring protector (RR = 0.83, 95% CI 0.38–1.83, P = 0.64).

There was a significant trend toward greater protective effect in studies using a dual-ring protector (relative risk = 0.31; 95% confidence interval, 0.15–0.58), rather than a single-ring protector (relative risk = 0.84; 95% confidence interval, 0.71–1.00).

Two high-quality analyses [ 61 , 62 ] have both noted a strong trend toward a greater protective effect with dual-ring variants when compared to devices constructed with a single external ring and associated semi-adhesive drape.
