Table 2. Mean Serum Creatinine Measures in the Study Population, Represented by Genotype Group and Presence or Absence of Diabetes

Diabetic patients are unevenly distributed among the three groups (P = 0.014) (table 1). Any variability in postoperative serum creatinine values related to diabetes is controlled for in the multivariate analysis (table 3).

Max = maximum; postop = postoperative.
