Discrimination and reclassification of ACS with various multivariable logistic regression models
| Old model | New model | AUC (95% CI) | P value-AUC | NRI (95% CI) | P value-NRI |
| Traditional factors* | - | 0.78 (0.75 to 0.81) | - | - | - |
| hs-cTnT | - | 0.80 (0.77 to 0.83) | - | - | - |
| Traditional factors* | +hs-cTnT | 0.81 (0.78 to 0.84) | 0.220 | 0.52 (0.40 to 0.64) | <0.001 |
| Traditional factors* | +Ceramides† | 0.81 (0.78 to 0.84) | <0.001 | 0.35 (0.23 to 0.47) | <0.001 |
| Traditional factors* +hs-cTnT | +Ceramides† | 0.87 (0.84 to 0.89) | <0.001 | 0.51 (0.39 to 0.64) | <0.001 |
P values AUC and p values NRI are for the difference between old models and new models. Bold used to highlight those p values <0.05.
*Traditional risk factors include hypertension, current smoker, LDL-C, CRP and NTproBNP levels.
†Ceramides include Cer(d18:1/24:1(15Z))/Cer(d18:1/24:0), Cer(d18:1/14:0) and Cer(d18:1/22:0).
LDL-C, CRP, NT-proBNP, hs-cTnT and ceramides levels are log transformed before analysis.
ACS, acute coronary syndrome; CRP, C reactive protein; hs-cTnT, high-sensitivity cardiac troponin T; LDL-C, low-density lipoprotein cholesterol; NT-proBNP, N-terminal pro-brain natriuretic peptide.
