Lactate Level Predicts Mortality in Patients with Upper Gastrointestinal Bleeding

Table 4

ROC analysis of lactate values and GBS for hospital mortality.

	AUC	SD	95% CI	Cutoff	Sensitivity	Specificity
GBS	0.683	0.078	0.530-0.835	13.5	66.7	71	0.021
Lactate	0.664	0.086	0.495-0.834	2.32	66.7	63.7	0.038

AUC: area under the curve; SD: standard deviation; CI: confidence interval; GBS: Glasgow-Blatchford Bleeding Score.
