Renal outcome after contrast-enhanced computerized tomography stratified by baseline serum uric acid: (A) Incidence of post-contrast acute kidney injury, defined by absolute increase of serum creatinine ≥0.3 mg/dL from baseline within 48 h or ≥50% within seven days after CCT. Chi-square tests were used to detect the significant differences among all pairs of populations with different ranges of serum uric acid, p < 0.001. Post-hoc analysis showed p = 0.033 in sUA 4–5.9 vs. 8–9.9 mg/dL, p = 0.028 in sUA 4–5.9 vs. ≥10 mg/dL, respectively. (B) Incidence of emergent hemodialysis within 30 days after contrast enhanced computerized tomography. Chi-square tests were used to detect the significant differences among all pairs of populations with different ranges of serum uric acid, p < 0.001. Post-hoc analysis showed p = 0.002 in sUA ≤ 3.9 vs. 8–9.9 mg/dL, p < 0.001 in sUA ≤ 3.9 vs. ≥10 mg/dL, p = 0.036 in sUA ≤ 3.9 vs. 6–9.9 mg/dL, p < 0.001 in sUA 4–5.9 vs. ≥10 mg/dL, p = 0.015 in sUA 6–7.9 vs. ≥10 mg/dL, respectively.
