Receiver operating characteristic (ROC) curves (unadjusted) for a sepsis and b in-hospital mortality. The areas under the ROC curves (AUROCs) for panel a are SIRS, 0.57 (95% confidence interval [CI], 0.53–0.61), p < 0.001; SOFA, 0.69 (95% CI, 0.64–0.73), p < 0.001; qSOFA, 0.67 (95% CI, 0.62–0.71), p < 0.001, and for panel b SIRS, 0.49 (95% CI, 0.44–0.54), p < 0.001; SOFA, 0.74 (95% CI, 0.69–0.79), p < 0.001; qSOFA, 0.65 (95% CI, 0.60–0.71), p < 0.001. AUC area under the curve, SIRS systemic inflammatory response syndrome, SOFA sequential (sepsis-related) organ failure assessment, qSOFA quick SOFA
