  1. CSA-AKI cardiac surgery associated acute kidney injury, OR odds ration, CI confidence interval, NYHA New York Heart Association, CABG coronary artery bypass grafting, eGFR estimated glomerular filtration rate, calculated by CKD-EPI formulae
  2. Both Interval ≤ 7d and Contrast used> 240 mg/kg are revealed as predictors in the unadjusted and adjusted logistic regression analysis
