Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Study appears to be randomised; however, French translation needed to confirm this
Allocation concealment (selection bias)	Unclear risk	French translation needed to determine if allocation was concealed.
Blinding (performance bias and detection bias) All outcomes	Low risk	Trial is double‐blind placebo‐controlled.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	French translation needed to judge this.
Selective reporting (reporting bias)	Unclear risk	French translation needed to judge this.
Other bias	Unclear risk	No imbalance in baseline characteristics. French translation needed to determine if there may be any other sources of bias.
