  1. aIQR = interquartile range; AUCROC = area under the receiver operating characteristic curve; DKA = diabetic ketoacidosis; 95% CI: 95% confidence interval; NA: not applicable. Data are from 2,074 patients admitted to four university-affiliated paediatric hospitals. Scores were calculated from 23,288 hours with one or more items of the seven-item Bedside PEWS score.
