: regression coefficient; 95% CI: 95% confidence interval for B; LI: limit inferior; LS: limit superior. p value ≤ 0.05 significant effect of the independent variable by the Wald statistic. value ≤ 0.05 indicates that the model is significant for predicting the dependent variable. Degree is as follows: 0: normal; 1: C-IMC thickening; 2: atheroma; 3: %; 4: stenosis 50-69%; 5: %; and 6 = occluded). Rutherford is as follows: 0: no COPAD; 1: Rutherford 0 (asymptomatic); 2: Rutherford 1; 3: Rutherford 2; 4: Rutherford 3; 5: Rutherford 4; and 7 = Rutherford 6. Gender (; ). Tobacco smoking (; ).
