Participation involves visits to Columbia Medical Center before and after surgery for blood tests and measurement of metabolism, body fat and muscle mass.
We provide compensation for participants’ time (up to $150 for each visit) and travel (up to $20 per visit). The total amount of compensation will depend on the study and the type of surgery you are having.
