Evaluation of the models. (A) ROC analysis was applied to calculate the AUC, which was used to assess the performance of the CHD model in training, random, and sequential testing. (B) The precision and recall curve of the CHD model in training, random, and sequential testing. (C) ROC analysis was used to calculate AUC, which was used to evaluate the performance of the CIS model in training, random, and sequential testing. (D) The precision and recall curve of the CIS model in training, random, and sequential testing. ROC, receiver operating characteristic; PR, precision and recall; AUC, area under the receiver operating characteristic curve; CHD, coronary heart disease; CIS, cerebral ischemic stroke.
