To investigate the effects of the timing of text message communication with participants on questionnaire return rates in a randomised trial. Participants will be randomised to receive all trial reminder text messages in the morning (approximately 8am) or in the evening (approximately 7pm).
Trial Forge will make trials more efficient by looking for marginal gains across all trial processes, from research question to implementation into routine care. It will encourage everyone connected with trials to be more sceptical of what we do by asking for the evidence behind all of our trial decisions.
