Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No description provided
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Attrition is described but analyses of differences between completers and non‐completers was not conducted.
Selective reporting (reporting bias)	High risk	Post‐treatment means and SDs are not provided for all measures.
