^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
^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
^d% weight loss calculated by % change from baseline to last recorded weight
^eUnadjusted mean loss among participants enrolled AND > 4 weeks attended
(In-person n = 2762; Online n = 7591)
Online: 28% reached > 5%; mean 2.6% (95%CI 2.5, 2.8); median 1.8 (IQR + 0.1, 5.6)
In-person: 41% reached > 5%; mean 5.0% (95%CI 4.7, 5.2); median 3.6 (IQR 0.1, 8.1)
