Construction and internal validation of the RRT predictive nomogram
AKI
REGRESSION
The nomogram for predicting the probability of RRT among AKI patients in ICU was constructed based on the multivariate logistic regression model (Fig. The nomogram prediction score of RRT among AKI patients in ICU. When using it, drawing a vertical line from each variable to the point axis for the score, then the points for all the parameters were added; finally, a line from the total point axis was drawn to correspond the probability of RRT at the bottom. The discrimination power of the nomogram was evaluated by the The receiver-operating characteristic (ROC) curves of the nomogram in the training cohort and validation cohortCalibration curve analysis in the training (
