From: Combined Thoracic Ultrasound Assessment during a Successful Weaning Trial Predicts Postextubation Distress Anesthes. 2017;127(4):666-674. doi:10.1097/ALN.0000000000001773 Figure Legend: Predictive values. Receiver–operating characteristic curves depicting the relationship between the proportion of true-positive findings and the proportion of false-positive findings. Estimation performances on prediction of likelihood of successful weaning from mechanical ventilation are represented as areas under the curve (AUC). Learning sample AUC: START, 0.921 (0.842 to 0.981); END, 0.951 (0.881 to 0.991). Test sample AUC: START, 0.972 (0.90 to 1.00); END, 0.920 (0.842 to 0.981).
