Note: NO as dependent variable and SOD, MDA, CRP, ox-LDL, LDL as independent variables, multiple stepwise regression analysis showed that serum SOD and CRP entered the equation, and the equation was y = 0.315 × 1-0.802 × 2-22.120 (y = NO, ×1 = SOD, ×2 = CRP; -22.120 was a constant). ET-1 as dependent variable and SOD, MDA, CRP, ox-LDL, and LDL as independent variables, multiple stepwise regression analysis showed that serum ox-LDL and SOD entered the equation, and the equation was y = 0.051 × 1-0.082 × 2 + 22.517 (y = ET-1, ×1 = ox-LDL, ×2 = SOD; 22.517 was a constant). NO/ET-1 ratio as dependent variable and SOD, MDA, CRP, ox-LDL, LDL as independent variables, multiple stepwise regression analysis showed that serum SOD and CRP entered the equation, and the equation was y = 0.102 × 1-0.316 × 2-13.151 (y = NO/ET-1 ratio, ×1 = SOD, ×2 = CRP; 13.151 was a constant). PCIPA as dependent variable and SOD, MDA, CRP, ox-LDL, LDL as independent variables, multiple stepwise regression analysis showed that serum SOD entered the equation, and the equation was y = 111.437-0.397 × 1 (y = PCIPA, ×1 = SOD; 111.437 was a constant).
