Receiver operating characteristics (ROC) curves for peripherally inserted central catheter (PICC)-associated bloodstream infection on the basis of the number of catheter days (red line) and clinical signs such as pain (blue dashed line), rash at the PICC insertion site (green pointed line), fever (orange dashed line), chills (purple dashed line), dyspnea (black dashed line). Area under the ROC curves (AUCs) are given with the 95% confidence interval (95% CI)
