Analysis of the receiver-operating characteristics curve for predicting mortality.

Notes: (A) In NHAP, the AUC was 0.69 for the CURB-65 scale, 0.67 for the PSI class, 0.65 for the B/A ratio, and 0.58 for the CRP level. (B) In CAP, the AUC was 0.76 for the CUBR-65 scale, 0.81 for the PSI class, 0.83 for the B/A ratio, and 0.64 for the CRP level.

Abbreviations: AUC, area under the curve; B/A ratio, blood urea nitrogen to serum albumin ratio; CRP, C-reactive protein; CURB-65 scale, confusion, urea, respiratory rate, blood pressure, and age ≥65 scale; PSI, pneumonia severity index.
