Comparison of the efficacy of three topical antiseptic solutions for the prevention of catheter colonization: a multicenter randomized controlled study.

Pairwise between-group comparisons of CRBSI showed no significant differences, but the risk exhibits a decreasing trend in the 0.5% and 1.0% CHG groups (0.5% CHG vs. 10% PVI: HR 0.63, 95% CI 0.18–2.22, p = 0.47; 1.0% CHG vs. 10% PVI: HR 0.41, 95% CI 0.10–1.63, p = 0.20).
