Model 1 predicting All-Cause mortality, comparison of (1) weighted vs unweighted, and (2) AUC vs AAC (3) at different set upper thresholds.

Model 1 predicting All-Cause mortality, comparison of (1) weighted vs unweighted, and (2) AUC vs AAC (3) at different set upper thresholds.针对全因死亡率预测任务的模型1，开展了以下三方面对比：(1) 加权方案与未加权方案的性能差异；(2) 受试者工作特征曲线下面积（Area Under the Receiver Operating Characteristic Curve, AUC）与AAC的性能差异；(3) 不同设定上限阈值下的模型表现差异。
