Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Used block randomisation
Allocation concealment (selection bias)	Unclear risk	Not reported
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Assessed the same outcomes (MYMOP, POMS) Quote: "all questionnaires were completed by the patients with the help of a research nurse, who had no involvement in their clinical care"
Incomplete outcome data (attrition bias) All outcomes	High risk	17 lost after 4 weeks (37.0%); reasons provided for drop‐out (n = 46)
Selective reporting (reporting bias)	Low risk	Quote: "completed the Profile of Mood State (POMS) questionnaire. This consists of six sub scales: tension, depression, anger, fatigue, confusion and vigour that combine to give an overall score of total mood of disturbance of between 0 and 76, a lower score indication less disturbance"
Size	High risk	n = 46
Other bias	Low risk	The age, sex, performance status, and prior experience of complementary therapy of those completing the study did not differ significantly between the 2 groups
