SD, standard deviation.
a
Therapy failure = catheter-related and maintenance-related complications.
b
Catheter-related complications are defined as leaking, infiltration/extravasation, breakage of the catheter, and phlebitis.
c
Maintenance-related complications are defined as accidental removal, tip migration, and occlusion.
d
Administrative censoring = death and neonates transferred out to another facility.
