Receiver operating characteristic curves for the prediction models. The receiver operating characteristic curves for successful extubation (a) and uneventful extubation (b) for models based on eight predefined physiological factors (POSE model) and RSBI alone (RSBI model). The AUCs are shown for each model, and the p-values represent the intergroup differences. POSE, Prediction of Successful Extubation; AUC, area under the receiver operating characteristic curve; RSBI, rapid shallow breathing index.
