Figure 1

(a) Retention (as a percentage of all 22,407 participants who enrolled) and (b) attendance (as a percentage of completers at each time point). JumpstartMD patients had a financial enticement to terminate the program early, which is not the case for clinical trials or subscription weight loss programs. Specifically, clinical trials subjects consent to participate in a no-cost program for a specified duration and subscribers prepay for a specified program length. In contrast, JumpstartMD patients pay a significant fee to receive their initial evaluation and recommendations and separately pay significant fees to participate on a month-to-month basis without obligation for as long as they perceive benefit from the program.
