Feasibility parameter	Proportion	95% CI
Cases consenting to enter the pilot RCT from those meeting entry criteria (screening questionnaires + DAI) – when there was a RAD criterion for eligibility	0.56	0.41–0.71
Cases consenting to enter the pilot RCT from those meeting entry criteria (screening questionnaires + DAI) – if RAD criterion is ignored for eligibility	0.45	0.33–0.57
Conversion rate into trial from total cases invited to take part overall (before screening)	0.9	0.6–0.12
