Fig. 2

The analysis of receiver-operating characteristics curve for predicting mortality. The area under the curve was 0.87 for BUN/ALB ratio, 0.73 for 1/ALB, and 0.85 for BUN. AUC, area under the curve; CI, confidence interval; BUN/ALB ratio, blood urea nitrogen to serum albumin ratio; ALB, albumin; BUN, blood urea nitrogen
