Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	"Random table".
Allocation concealment (selection bias)	Unclear risk	No details reported.
Blinding (performance bias and detection bias) All outcomes	Low risk	"Double‐blind"; "The syrups were identical in appearance and flavor and were packaged in identical containers. Randomized patient numbers were labeled on the bottles to maintain the double blind design".
Incomplete outcome data (attrition bias) All outcomes	Low risk	94% (81/85) of randomized participants were evaluated. Inclusion of all randomized participants (number evaluable/number randomized): 94% (81/85).
Selective reporting (reporting bias)	Low risk	Pre‐specfied outcomes reported.
Other bias	Low risk	No obvious other source of bias.
