Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Comment: no information on random sequence generation other than 'patients were randomly assigned'.

Incomplete outcome data (attrition bias) All outcomes	Low risk	Comment: all patients that were randomised completed the study: for all randomised patients outcome was presented.

Several outcomes were presented in the results section, unclear if this was all that was measured. Furthermore, it is unclear how it was measured.
Other bias	Low risk	No other source of bias could be detected
Blinding of participants and personnel (performance bias) All outcomes	High risk	Comment: not mentioned, probably not done.
Blinding of outcome assessment (detection bias) All outcomes	High risk	Comment: not mentioned, probably not done.
