SECONDARY outcome

Timeframe: baseline to end-of-treatment (6 months)

Population: measure was added to study while in process

Adherence to prescribed medication regimen rated by caregiver on a 1 (0%) to 5 (100%) scale. Higher scores indicate better adherence. Values in statistical table below are least square estimates, and thus may be slightly out-of-range of actual respondent choices on scale.
