From: Indicators of different outcomes after prolonged weaning
ROC curves for each weaning outcome. Shows the ROC curves for each weaning outcome: weaning category 3a (successful weaning without non-invasive Ventilation [NIV]) in the upper left quadrant, weaning category 3b (successful weaning with NIV) in the upper right quadrant, weaning category 3cI (failed weaning with continued IMV) in the lower left quadrant and weaning category 3cII (death) in the lower right quadrant. They show an acceptable AUC (area under curve) for each category (3a 0.79, 3b 0.77, 3cI 0.72, 3cII 0.74) with a significance < 0.001 (see Table 3).
