Definition of acute kidney injury is absolute increase of serum creatinine ≥0.3 mg/dL from baseline within 48 h or ≥50% within seven days after contrast-enhanced computerized tomography. Model 1, adjusted by the comorbidities listed in Table 1. Model 2, adjusted by hemoglobin, serum albumin, bilirubin, uric acid, usage of diuretics, usage of ACE inhibitors/ARB, usage of N-acetylcysteine, usage of sodium bicarbonate, usage of non-steroidal anti-inflammatories, plus covariates listed in Model 1.
