Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment location: clinical research unit at the NIDKK (Phoenix, AZ, USA)

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Upon admission, all participants were placed on a weight maintaining diet (containing 50% of energy as carbohydrate, 30% as fat and 20% as protein). Body composition was measured by dual-energy x-ray absorptiometry. At least 3 days after admission and after a 12 h overnight fast a 2-h 75 g OGTT was performed to exclude diabetes.

Reporting Groups
Salsalate The intervention was salsalate (3g/day) for 7 days
Placebo Placebo for 7 days.
