CRP and hypertensive disorder: Among patients with hypertension, the serum levels of CRP (each 0.1 mg/dL increment, odds ratio [OR]: 1.649, 95% confidence interval [CI]: 1.138–2.389, p = 0.008) and PCS (OR: 1.154, 95% CI: 1.013–1.315, p = 0.031) were identified as independent predictors for PAD (Table 2).
