aSeq: Sequential self-monitoring intervention arm.
bThis is the primary comparison; the App-Only arm is the reference group.
cOne additional participant was omitted in analyses (App-Only arm) at 6-months due to becoming ineligible after the intervention period and before 6-months.
dBMI: body mass index.
