P values present the results of the multivariable logistic regression

Variables with P < 0.1 in the univariate analysis were entered into the multivariate analysis model

BMI body mass index, CAD coronary artery disease, CI confidence interval, ESR erythrocyte sedimentation rate, F/Hx family history, TC total cholesterol, CRP C-reactive protein, F/Hx family history, OR odds ratio

P value of < 0.05 was considered statistically significant
