Table 3 Multivariable analysis to assess the independent impact of BMI on postoperative AKI in patients with ADTIAD using non-adjusted and adjusted logistic regression model

From: Body mass index is an independent predictor of acute kidney injury after urgent aortic arch surgery for acute DeBakey Type I aortic dissection

  1. ADTIAD Acute DeBakey Type I Aortic Dissection, AKI Acute Kidney Injury, AMI Acute Myocardial Infarction, BMI Body Mass Index, eGFR estimated Glomerular Filtration Rate, OR Odd Ratio, 95% CI 95% Confidence Interval, CPB time Cardiopulmonary Bypass time, PRBCs Packed Red Blood Cells
  2. Model I: adjust for none
  3. Model II: adjust for age; sex
  4. Model III: adjust for age; sex; previous cerebrovascular disease; smoking history; renal artery dissection; eGFR; AMI; respiratory failure; CPB time; intraoperative blood loss; reoperation for bleeding; intraoperative amount of PRBCs
