-------------------------------------------------------------------------------- 6. RECOMMENDATIONS -------------------------------------------------------------------------------- - For closed populations, use multi-channel invitations (email + SMS reminder). - If resources are limited, prefer SMS over email or in-app messaging. - Avoid relying solely on in-app notifications due to low visibility. - Future trials should test timing optimization (e.g., send reminders at 24h instead of 48h).
