Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Adequate sequence generation?	Unclear risk	NS
Allocation concealment?	Unclear risk	NS
Blinding? Treatment provider	High risk	Acupuncturist aware of treatment group
Blinding? Outcome assessor	Unclear risk	Not relevant as outcome was patient‐reported
Incomplete outcome data addressed? All outcomes	High risk	Drop‐outs not described
Free of selective reporting?	Unclear risk	No protocol available
Free of other bias?	Low risk
No signs of variance inequality or skewness?	Low risk	SD x 1.64 < mean
Trial size > 49?	High risk	N = 32
Clearly concealed allocation + trial size > 49 + drop‐out max 15%	High risk	Trial size < 49
