Using baseline CMI to construct 9 types of machine learning models. Construction and comparison of multiple machine learning models were conducted for the prediction of rapid decline in kidney function and CKD, utilizing ROC curve analysis for the machine learning algorithms on the training set and the validation set. (A) Training set of rapid decline in kidney function; (B) Validation set of rapid decline in kidney function; (A) Training set of CKD; (B) Validation set of CKD
