We are now conducting a follow up survey, taking into account only 2 treatment arms: details are given in the follow-up pre-analysis plan
Planned Number of Observations Approximately 2,000 participants Approximately 2,000 participants (in standard study); In follow-up much smaller as we only consider 2 treatment arms (for budgetary reasons)
