From: Establishment and validation of prognosis model for patients with cerebral contusion
The ROC curve plotted showed that the AUC value of the training group was 0.87, and the AUC value of the validation group was 0.93, indicating the good prediction performance of the nomogram in the training and validation cohort (A and B. In internal and external validation of nomographic prediction of poor outcomes for CC, the calibration curves showed agreement between the observed outcomes for patients with CC (C and D). the dotted black line represents the predictive ability of the nomogram, a closer fit to the diagonal dotted black line represents a better prediction
