Figure 2.

(A) Receiver operating characteristic curves and (B) precision-recall curves of the developed machine learning models to predict successful weaning from mechanical ventilation within 14 days of intubation. The area under receiver operating characteristics curves (AUROCs) and area under precision-recall curves (AUPRCs) and their 95% CIs for all 6 models are shown in the legends. For comparability, the random classifier is indicated by a black dashed-dotted line. CBC: CatBoost classifier; RFC: random forest classifier; RLRC: regularized logistic regression classifier; SAPS II: Simplified Acute Physiology Score II; SOFA: Sequential Organ Failure Assessment; VC: voting classifier.
