FGF21 and Hypertension: Table 3 shows that the cfPWV value was positively correlated with age (r = 0.238, p = 0.006), body fat mass (r = 0.195, p = 0.026), hypertension (r = 0.223, p = 0.008), SBP (r = 0.331, p < 0.001), DBP (r = 0.231, p = 0.008), log-TG (r = 0.281, p = 0.001), log-glucose (r = 0.241, p = 0.006), log-HbA1c (r = 0.218, p = 0.013), log-creatinine (r = 0.281, p = 0.002), log-UACR (r = 0.227, p = 0.015), and log-FGF-21 (r = 0.338, p < 0.001), but it was negatively correlated with eGFR (r = −0.314, p = 0.001) by simple linear regression analysis.
