Model performance: calibration and discrimination of original model. A, The model calibration assessed with a fitted curve based on Loess regression with 95% confidence interval. Perfect calibration is illustrated by the dotted line. Triangles represent deciles of predicted probability and grey points represent predicted probabilities of individual patients. Goodness of fit was assessed with the Hosmer-Lemeshow test. B, Model discrimination assessed with the receiver operating characteristic curve. AUC, area under the curve; ICU-AW indicates intensive care unit–acquired weakness.
