Incidence densities of CLABSI per 1000 CL days with any pathogen (A) and gram-positive bacteria (B) per study group in baseline and intervention period. Chlorhexidine (CHG, wide dashed line in blue), octenidine (OCT, small dashed line in red) and control group (routine care = water and soap, solid line in green). Months 1–12 represent the baseline, months 13–24 the intervention period. The latter have been shown elsewhere [15]. CLABSI, central line associated bloodstream infections.
