Participant Flow

Accrual for RCT began in 1999 and ended in 2008. All subjects were screened at the NIH Clinical Center.

Most subjects screened but not enrolled (101) did not have an obesity-related comorbid condition (i.e., hypertension or dyslipidemia). 16 met a medical exclusion, and 13 declined participation after undergoing initial evaluation.
