Figure 3. Association between RDW-SD and serum NSE level. A linear relationship between RDW-SD and serum NSE level was detected after adjusting for gender, age, hypertension, diabetes, CHD, neutral cells, platelets, LDL, creatine, homocysteine, prothrombin time, antihypertensive drugs, lipid-lowering drugs, and antiplatelet drugs. Solid lines represent the fitting curve, and dotted lines represent the corresponding 95% CI.
