Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	"Randomization was performed using a computer‐generated random number table [...]"
Allocation concealment (selection bias)	Low risk	"[...] random number table with group assignments that was sent to the clinics [...], which was used sequentially to order group assignments during recruitment. The order of randomization was verified with the hospital date of admission records for radiotherapy at intervals to make sure that field personnel had not altered the sequence of randomization to suit allocation of consenting participants into the 2 study arms."
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	No information on blinding
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No information on blinding of patient‐reported outcomes
Incomplete outcome data (attrition bias) All outcomes	High risk	30% dropout in control group, no dropout in yoga group
Selective reporting (reporting bias)	Low risk	No protocol available but no hint of selective reporting
Other bias	Low risk	No hint of other bias
