Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Method of randomization not stated.
Allocation concealment (selection bias)	Unclear risk	Method of concealment not stated.
Blinding of participants and personnel (performance bias) All outcomes	Low risk	Non‐blinding is not likely to affect the outcomes of interest as they are objectively assessed.
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Those who administered the intervention were not blinded but non‐blinding of outcome assessment is not likely to affect the outcomes of interest as they are objectively assessed.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	No study protocol available.
Selective reporting (reporting bias)	Unclear risk	No data on live births.
Other bias	Unclear risk	Insufficient information to make a conclusive judgement.
