  1. Data are expressed as means ± standard deviation. Paired adipose samples were available for all 15 before weight loss and for 13/15 after weight loss
  2. aHbA1c is reported as % using DCCT (Diabetes Control and Complications Trial) units
  3. bBlood pressure data was not available for samples in the validation cohort
