  1. Abbreviations; RR, relative risk; CI, confidence interval; CA-AKI, contrast-associated acute kidney injury.
  2. Adjusted for age, sex, admission status, comorbidity diseases including DM, hypertension, coronary artery disease, and heart failure, serum creatinine level, serum BUN level, serum tCO2.
  3. Hypochloremia; chloride level less than 98 mEq/L at baseline.
  4. Normochloremia; chloride level between 98 to 110 mEq/L at baseline.
  5. Hyperchloremia; chloride level over 110 mEq/L at baseline.
