Receiver Operating Characteristic Curve of qSOFA and qSOFA-CRP Models Based on Infection Status. a. Area under the receiver operating characteristic curve(AUROC) values for qSOFA and qSOFA-CRP scores ≥ 2 in the infection group: qSOFA (0.65, 95% CI 0.54–0.75) and qSOFA-CRP (0.69, 95% CI 0.61–0.76). b. AUROC values for qSOFA and qSOFA-CRP scores ≥ 2 in the non-infection group: qSOFA (0.60, 95% CI 0.49–0.71) and qSOFA-CRP (0.71, 95% CI 0.62–0.80).; ROC, receiver operating characteristic curve; qSOFA, quick sequential organ failure score; qSOFA-CRP, modified qSOFA with CRP criteria added; CRP, C-reactive protein
