Fig. 2From: Nomogram for the prediction of postoperative hypoxemia in patients with acute aortic dissectionModel calibration and discrimination. The predicted probability by the logistic regression model conforms well to the observed probability well. In the plot, the idea line is consistent with the Logistic calibration line. The discrimination was measured by AUC of 0.869 (95% CI: 0.802 to 0.936)Back to article page
