Comparison of the ability of three scoring systems to predict inpatient mortality, intensive care unit admission and length of stay

	Number of cases	AUC (95% CI)	p-value
Inpatient mortality
Waterlow score	250	0.73 (0.59–0.86)	0.0007
CRP at 48h	233	0.66 (0.52–0.79)	0.021
Glasgow score	106	0.62 (0.39–0.85)	0.288
Intensive care unit admission
Waterlow score	222	0.65 (0.50–0.80)	0.049
CRP at 48h	209	0.87 (0.79–0.95)	<0.0001
Glasgow score	96	0.68 (0.51–0.85)	0.080
Length of stay >7 days
Waterlow score	249	0.64 (0.57–0.71)	0.0002
CRP at 48h	232	0.79 (0.73–0.85)	<0.0001
Glasgow score	106	0.65 (0.55–0.75)	0.0081

AUC = area under the curve; CI = confidence interval; CRP = C-reactive protein
