Risk of bias
Bias	Authors' judgement	Support for judgement
Adequate sequence generation?	Low risk	Computer generated
Allocation concealment?	Unclear risk	Reported that envelopes used but not reported if they were opaque
Blinding? All outcomes	Low risk	All necessary researchers were blinded
Incomplete outcome data addressed? All outcomes	Unclear risk	No reason for missing data reported (20 patients (18%) lost to follow up)
Free of selective reporting?	Unclear risk	Insufficient information provided
Free of other bias?	High risk	Baseline differences in x‐ray rates between intervention groups; study underpowered
