Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Randomised by computer generated random numbers created by study coordinator
Allocation concealment (selection bias)	Low risk	Allocation kept in sealed opaque envelopes until opened on day 7 by ward nurses
Blinding of participants and personnel (performance bias) All outcomes	Low risk	No blinding but unlikely to impact outcome
Blinding of outcome assessment (detection bias) All outcomes	High risk	No blinding
Incomplete outcome data (attrition bias) All outcomes	Low risk	No missing outcome data, however CONSORT diagram not included
Selective reporting (reporting bias)	Low risk	No study protocol data but all reported outcomes are accounted for
Other bias	Low risk	The study appears to be free of other biases
