  1. ap values estimating proportion achieving implementation outcome using chi-2 tests
  2. bParticipants were considered referred after they registered and matched to a lifestyle change program per their preferences. Participants that lived more than 25 miles from closest in-person program were limited to online programs
  3. cAttendance measured by platform: online: composite of curriculum delivery, health coach interaction, peer support and self-tracking that is measured equivalent of in-person hour attendance and agreed upon between the payer and program; In-person: physical attendance of hour long weekly session
  4. d% weight loss calculated by % change from baseline to last recorded weight
  5. eUnadjusted mean loss among participants enrolled AND > 4 weeks attended
  6. (In-person n = 2762; Online n = 7591)
  7. Online: 28% reached > 5%; mean 2.6% (95%CI 2.5, 2.8); median 1.8 (IQR + 0.1, 5.6)
