The n for each laboratory is as follows: fasting glucose (n = 34); 1-hour glucose (n = 32); 2-hour glucose (n = 33); fasting C-peptide (n = 28); fasting insulin (n = 27); HbA1c (n = 34).

^aModel 1 is unadjusted; model 2 is adjusted for age.

^bPreoperative glycemic measures are dichotomized at their median values.

^cP < 0.05.
