Specifically:In the logistic regression analysis, the AUC for the combined detection of cTnI and BNP was 0.879 (95% CI: 0.812–0.946, P < 0.001), which is consistent with the original analysis (AUC: 0.883);In the subgroup analysis by age (≤1 years vs. >1 years), the AUC values were 0.865 (95% CI: 0.790–0.928, P = 0.324) and 0.881 (95% CI: 0.810–0.942, P = 0.287), respectively;In the subgroup analysis by CHD type (simple type vs. complex type), the AUC values were 0.870 (95% CI: 0.795–0.930, P = 0.412) and 0.884 (95% CI: 0.813–0.947, P = 0.376), respectively. Here, TNNI3 is linked to coronary artery disorder.
