Fig. 2From: Development and validation of a Score for Preoperative Prediction of Obstructive Sleep Apnea (SPOSA) and its perioperative outcomesReceiver operating characteristic (ROC) curve for prediction of obstructive sleep apnea. a ROC curve was performed for the logistic regression model derived from significant independent predictors (AUC 0.8218). b A second ROC curve was fitted based on the composite prediction score derived from our prediction model (AUC 0.8211)Back to article page
