Risk factors and a nomogram for predicting severe acute kidney injury in pediatric sepsis: a retrospective study.

Severe acute kidney injury occurred in 228 patients (23.1%).

The logistic regression model showed moderate discrimination with an area under the ROC curve (AUC) of 0.782 ( 95% CI = 0.744-0.819).

The corresponding nomogram achieved an AUC of 0.761 ( 95% CI = 0.724-0.797).

At their optimal cutoff values, the model and nomogram yielded sensitivities of 60.10% and 62.70%, specificities of 85.40% and 80.80%, and Youden indices of 0.455 and 0.435, respectively.
