Fig. 6From: Development and validation of a nomogram for predicting in-hospital mortality in ICU patients with infective endocarditisCalibration curves of the training cohort (A) and validation cohort (B) for the nomogram. The x-axis represents the nomogram-predicted probability, and the y-axis represents the actual probability of the nomogram. The diagonal line represents the perfect prediction of the ideal model. The dashed line represents the nonparametric calibration curve, the solid line represents the calibration curve of logistic regressionBack to article page
