  1. APACHE, Acute Physiology and Chronic Health Evaluation; AUC, area under the receiver operating characteristic curve; CI, confidence interval; MEDS, Mortality in Emergency Department Sepsis; MOD, multiple organ dysfunction; PIRO, predisposition, infection, response, and organ dysfunction; SE, standard error. Compared with PIRO: **P < 0.01; *P < 0.05.
