CST3 and Hypertension: The results demonstrated that norepinephrine (OR = 1.003, 95% CI: 1.001–1.007), normetanephrine (OR = 1.009, 95% CI: 1.002–1.015), metanephrine (OR = 1.026, 95% CI: 1.010–1.042), serum uric acid (OR = 1.003, 95% CI: 1.003–1.007), serum creatinine (OR = 1.036, 95% CI: 1.020–1.053), duration of hypertension (OR = 1.088, 95% CI: 1.021–1.160), and cystatin C (OR = 12.367, 95% CI: 4.136–39.977) were independent risk factors for organ damage in hypertensive patients (all P < 0.05) (Table 3).
