Usefulness of N-terminal pro-B-type natriuretic peptide in patients admitted to the intensive care unit: a multicenter prospective observational study

Table 4 The area under the ROC curve in prediction of hospital mortality

	AUC	95% CI	p-value
NT-pro-BNP	0.671	0.639-0.704	<0.001
SAPS3	0.828	0.805-0.852	<0.001
SAPS3 + ln_NT-pro-BNP (continuous variable)	0.831	0.808-0.855	<0.001
SAPS3 + ln_NT-pro-BNP (categorical variable)	0.835	0.812-0.858	<0.001

ROC = Receiver operating characteristic; AUC = area under the curve; CI = confidence interval; SAPS 3 = Simplified Acute Physiology Score (SAPS) 3.
Natural-log-transformed (ln) NT-pro-BNP was used as the continuous variable or divided by the quartile and used as the categorical variable.
