Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Paper states "patients were randomly assigned"

Selective reporting (reporting bias)	Low risk	None apparent
Other bias	Low risk	None apparent
Protection against contamination	Low risk	25% control consultations monitored to check for contamination
Reliable primary outcomes	Low risk	Validated measures and automated tests
Baseline measurement	Low risk	Groups comparable at baseline
