Fig. 2From: Peripherally inserted central catheters have a protective role and the effect of fluctuation curve feature in the risk of bloodstream infection compared with central venous catheters: a propensity-adjusted analysisRestricted cubic spline of CLABSI risk. A OR value increased rapidly in the first 8 calendar days after CVC insertion. However, after the 8th calendar day the OR value became stable. B In the first 4 calendar days after PICC insertion, the OR value increased day by day, reached a relatively high point on the 4th calendar day, and decreased from days 5 through 8. However, after the 8th calendar day the OR value began to increase day by day againBack to article page
