In univariate linear regression analysis, gender (β = −0.0873, p = 0.0071), PD duration (β = 0.0028, p = 0.0075), hypertension (β = 0.1345, p < 0.001), DM (β = 0.1284, p < 0.001), smoking history (β = 0.1464, p < 0.001), IV iron therapy (β = −0.094, p = 0.0079), Hct (β = 0.1275, p = 0.041), Hgb (β = 0.0021, p = 0.043), TSAT (β = 0.0023, p = 0.005), ferritin (β = 0.0009, p < 0.001), CRP (β = 0.0362, p < 0.001), and hepcidin (β = 0.0057, p = 0.012) were significant predictors of CIMT. The gene discussed is HAMP; the disease is hypertensive disorder.
