Fig. 9From: Acute renal injury after aortic arch reconstruction with cardiopulmonary bypass for children: prediction models by machine learning of a retrospective cohort studyDecision curve analysis for the model combined with renal ischemia. They-axis measures the net benefit. The y-axis measures the net benefit. The grey line represents the assumption that all patients have AKI. The red line (model1) represents the model without renal ischemia. The blue line (model2) represents the model with renal ischemiaBack to article page
