Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	High risk	Randomised by odd/even last digits of social security number
Allocation concealment (selection bias)	Low risk	Due to randomisation type no influence of allocation
Blinding of participants and personnel (performance bias) All Outcomes/Outcome 1	Unclear risk	Participants were not told to which group they were allocated but would most likely know due to the study procedures.
Blinding of outcome assessment (detection bias) All Outcomes/Outcome 1	Low risk	BP measured by blinded nurses
Incomplete outcome data (attrition bias) All outcomes	Low risk	Between group attrition < 10%. Overall competion rate 92%.
Selective reporting (reporting bias)	Low risk	All outcomes reported
Other bias	Low risk	None identified
