Based on the extent of coronary artery stenosis, participants were divided into a CHD group (stenosis \u226550%, n = 329) and a control group (stenosis &amp;lt;50%, n = 109).

Independent risk factors for CHD were analyzed using binary logistic regression. Receiver operating characteristic curve analysis was conducted to evaluate the diagnostic discrimination (area under the curve) of each biomarker for concurrent assessment of lesion severity. Statistical analysis was performed using SPSS 27.0. Continuous data were compared using t-tests or nonparametric tests; categorical data were compared with \u03c7\u00b2 tests.
