Fig. 3From: The prediction of in-hospital mortality in chronic kidney disease patients with coronary artery disease using machine learning modelsDiscrimination performance of eight machine learning models. A ROC of eight machine learning models. B P-R curves of eight machine learning models. The GBDT algorism exhibited the best performance both in ROC and P-R curves.
