Participant Flow

Participants were recruited based on physician referral at 6 sites between Feb 2018 and Jan 2024. The first participant was enrolled on 5 Mar 2018 and the last participant was enrolled on 10 Jan 2023.

Approximately 80 subjects (including 20 roll-in subjects) in 10 sites planned to be enrolled. The sample of primary cohort is 60. The sample of roll in cohort depends on the site number. 2 roll-in subjects per site is required. Actually 6 site participated in this study, totally there are 72 subjects in all.
