Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	The trial was described as being randomised, but it was unclear how the sequence was generated.
Allocation concealment (selection bias)	Low risk	The allocation was concealed using sealed envelopes.
Blinding of participants and personnel (performance bias) All outcomes	High risk	The trial was described as not blinded.
Blinding of outcome assessment (detection bias) All outcomes	High risk	The trial was described as not blinded.
Incomplete outcome data (attrition bias) All outcomes	High risk	Above 5% dropouts and the trial did not use proper methodology for intention‐to‐treat analysis.
Selective reporting (reporting bias)	Unclear risk	No protocol could be obtained, and the trial did not report all‐cause mortality or serious adverse events.
For‐profit bias	Low risk	It was unclear how the trial was funded.
Other bias	Low risk	The trial appeared to be free of other components that could put it at risk of bias.
