Completers attended ≥4 sessions in phase 1, ≥2 sessions in phase 2 and ≥6 sessions in phase 3.
Duration of phases: phase 1, 16 weeks; phase 2, 3 months (may be repeated); phase 3, 12 months.
*Phase 3 completers must have completed phase 1, and phase 2 if they entered it.
BOCF, baseline observation carried forward; LOCF, last observation carried forward.
