Receiver operating characteristic (ROC) curves of the proposed RF model and existing scoring systems for mortality prediction with Dataset 1 (the patients with complete records of the existing scoring systems from MIMIC-III database; namely, subset of Dataset 2). (A) in-hospital mortality prediction; (B) 30-day mortality prediction; (C) 1-year mortality prediction. RF, random forest; MIMIC-III, Medical Information Mart for Intensive Care database; OI, Oxygenation Index; OSI, Oxygenation Saturation Index; SAPS-II, Simplified Acute Physiology Score II; SOFA, Sepsis-related Organ Failure Assessment.
