Adjusted OR (95% CI) and p-values for the hemodynamic parameter are from MLR adjusted for age, diabetes duration, hypertension duration, sex, BMI, and smoking status. “Significant covariates” lists adjustment variables with p < 0.05 in the corresponding model
Values are mean ± SD. MWU: Mann–Whitney U test (PAD vs non-PAD)
