FGF21 and diabetes mellitus: The cfPWV value was positively correlated with age (r = 0.194, P=0.027), systolic blood pressure (r = 0.186, P=0.034), pulse pressure (r = 0.272, P=0.002), logarithmically transformed CRP (log-CRP, r = 0.242, P=0.006), log-FGF-21 (r = 0.335, P < 0.001), and the presence of DM (r = 0.378, P < 0.001).
