Data are presented as the median (minimum–maximum) or as n (%).

The p values for body weight, gestational age, and postnatal age were analyzed using the Mann–Whitney U test.

The p values for catheter type (8-cm PICC, CVC, UVC, UAC, and PAC) and the number of catheters were analyzed using Fisher’s exact test, and other categorical variables were analyzed using the χ2 test.

PIVC: peripheral intravenous catheter; PICC: peripherally inserted central catheter; CVC: central venous catheter; UVC: umbilical venous catheter; UAC: umbilical arterial catheter; PAC: peripheral arterial catheter; G: gauge.

Whether the 8-cm PICC was used as a long PIVC or a PICC is unclear.
