Kaplan-Meier curves for hypertension among quartiles of serum uric acid (SUA) levels. Baseline quartiles of SUA were defined as follows: first quartile, <4.69 mg/dl (<P25); second quartile, 4.69–5.58 mg/dl (P25~); third quartile, 5.58–6.52 mg/dl (P50~); and fourth quartile, ≥6.52 mg/dl (≥P75). a Baseline, all subjects (log-rank test P-value <0.01, <P25 vs. other quartiles). b Follow-up, all subjects (log-rank test P-value <0.05, <P25 vs. other quartiles). c Baseline, normal-eGFR subjects only (log-rank test P-value <0.01, <P 25 vs. other quartiles)
