Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Described as randomised ‐ method of randomisation is not reported.
Allocation concealment (selection bias)	Low risk	"packages of medication were identified only by a code which was kept in the pharmacy until the conclusion of the study" (p.298).
Blinding of participants and personnel (performance bias) All outcomes	Low risk	"packages of medication were identified only by a code which was kept in the pharmacy until the conclusion of the study" (p.298).
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Described as double‐blind, however no further details reported regarding rater blinding.
Incomplete outcome data (attrition bias) All outcomes	Low risk	No evidence of incomplete data.
Selective reporting (reporting bias)	Low risk	No evidence of selective reporting.
Other bias	High risk	Small short study.
