PRIMARY outcome

Timeframe: 24 months (immediate arm) and 15 months (delayed arm)

Population: For biomedical outcomes, a treatment emergent cohort was defined. Participants entered the TE cohort with first dispense and exited with the first occurrence of: (1) completion of follow-up, (2) 30 days after permanent drug interruption, or (3) 30 days after last visit. For delayed arm participants,time before initiation of drug was excluded.
