ROC curves and AUCs, Calibration plots and Kaplan–Meier survival curves of the model. (A) ROC curves and AUCs of the nomogram in the training and external validation cohort. (B) Calibration plots of the nomogram-predicted probability of 7-day survival in the training and validation cohorts. Nomogram-predicted survival is plotted on the x-axis, with observed survival on the y-axis. Dashed lines along the 45-degree line through the origin point represent the perfect calibration models in which the predicted probabilities are identical to the actual probabilities. (C) Kaplan–Meier survival curves of different risk groups in the training and external validation cohorts.
