Notes
Risk of bias
Item	Authors' judgement	Description
Random Sequence generation ok?	No	Consultation sequence is part of allocation, so it is possible to predict who will get control and who gets intervention
Allocation concealment?	No	As above
Blinding of participants and personnel ok?	Yes	Participants blinded but not doctors, but hard to avoid this
Blinding of outcome assessment ok?	Yes	Main outcome for review is recruitment, which is objective. Also some independent assessment though probably not necessary for recruitment
Incomplete outcome data handled ok?	Yes	Adequate
Free of selective reporting?	Yes	Recruitment reported and this is only outcome needed for review
Was the study free of other bias?	Yes	No other biases apparent
Overall bias?	Yes	High risk of bias
