The GGT1 G allele was significantly associated with the risk of a high baPWV (≥1,750 cm/sec) in the T2DM subjects (OR 1.80, P = 0.008), in addition to age, hypertension, the diabetes duration, low HDL-C (<1.0 mmol/L) and drinking in the univariate models (Table 3). Here, GGT1 is linked to hypertensive disorder.
