1. Analysis of catheter-related bloodstream infection in trials comparing chlorhexidine/silver sulfadiazine-impregnated central venous catheters with nonimpregnated catheters. The diamond indicates odds ratio (OR) and 95% confidence interval (CI). Studies are ordered by increasing mean duration of catheterization in the treatment group. The size of the squares is inversely proportional to the variance of the studies.
