Receiver operating characteristic (ROC) curve analysis. The analysis showed that smoking status (area under the curve [AUC]: 0.60, 95%CI: 0.50, 0.71), presence of chronic obstructive pulmonary disease (COPD) (AUC: 0.60, 95%CI: 0.49, 0.70), C-reactive protein (CRP) levels (AUC: 0.68, 95%CI: 0.57, 0.79) and Acute Physiology and Chronic Health Evaluation (APACHE) II scores (AUC: 0.69, 95%CI: 0.60, 0.79) could predict increased risk from acute respiratory distress syndrome (ARDS) in sepsis patients. The combination of the four risk factors had a greater predictive value than each individual factor (AUC: 0.80, 95%CI: 0.71, 0.89).
