Risk of bias
Bias	Authors' judgement	Support for judgement

Allocation concealment (selection bias)	Unclear risk	No information
Blinding of participants and personnel (performance bias) Subjective outcomes	High risk	Blinding not feasible
Blinding of participants and personnel (performance bias) Objective outcomes	High risk	Blinding not feasible
Blinding of outcome assessment (detection bias) Subjective outcomes	High risk	Unlikely to be blinded
Blinding of outcome assessment (detection bias) Objective outcomes	High risk	Unlikely to be blinded
Incomplete outcome data (attrition bias) Subjective outcomes	Low risk	1 participant withdrawn from wool and crepe group (4% of 25 participants). Unlikely to be a problem
Incomplete outcome data (attrition bias) Objective outcomes	Low risk	1 participant withdrawn from wool and crepe group (4% of 25 participants) Unlikely to be a problem
Selective reporting (reporting bias)	High risk	Incompletely reported only in a poster abstract
Other bias: major imbalance in baseline characteristics	Unclear risk	Baseline characteristics not reported by group
