Performances of scores were calculated from a predictive equation derived on the development sample; sensitivity and specificity were calculated using thresholds measured on the development sample.
AUC, area under the receiver-operating curve; Bedside PEWS, Bedside Paediatric Early Warning System; PPV, positive predictive value; NPV, negative predictive value; PAWS, Paediatric Advanced Warning Score; PEWS, Paediatric Early Warning Score.
