^aNHS Trusts 1, 2 and 3 each had one midwife whose questionnaire was reported to be lost in the post at baseline, the number in the table relates to the number we received back rather than the number of midwives who reported they had already sent it when we followed up non-responders
^bWe only collected follow-up date for midwives at one time point rather than two time points as per the protocol given the poor retention rate in the intervention arm and the need to prioritise exploring this further with non-responding midwives rather than burden them with further questionnaire data collection
