Adherence to the medication regimen before the
primary outcome was reached or the study was
completed ranged from 84% at month 8 to 57%
at month 60 but did not differ significantly across
treatments (Section G in the Supplementary Appendix).
Sex, race or ethnic group, age, baseline
BMI, and baseline glycated hemoglobin level did
not differ significantly between participants who
adhered to the study regimen and those who did
not. When the analysis of the primary outcome
included only participants who adhered to the medication
regimen, the findings were unchanged.
The rate of attendance at lifestyle program visits
during the first 24 months was 75.2%; 53.6% of
participants met the preplanned target of attending
75% or more of visits over these 2 years. There
was no significant difference in the occurrence of
glycemic failure or BMI change between participants
who met the target for visits and those who
did not.
