Cut-off points for continuous variables determined using Receiver Operating Characteristic curves: Antibiotic length: 7 days (Sn 72.5%, Sp 71.0%); Inotropic length: 5 days (Sn 75.7%, Sp 59.5%); days on mechanical ventilation (MV): 10 (Sn 84.1%, Sp 73.1%); Length of stay in PICU (paediatric intensive care unit): 15 days (Sn 88.4%, Sp 74.8%); Length of stay in hospital: 20 days (Sn 90.0%, Sp 59.1%).
