ALB and diabetes mellitus: As shown in Table 2, NCV at all sites significantly and negatively correlated with age, duration of diabetes, systolic blood pressure (SBP), FPG, HbA1c, HDL-C, and urine albumin (p <0.05 at least), although some of the correlation, such as SBP and MCV (tibial and median forearm) as well as HDL-C and median (wrist), were marginal (all p <0.1 at least).
