Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Allocation concealment (selection bias)	Unclear risk	Allocation concealment not documented
Blinding (performance bias and detection bias) All outcomes	Low risk	Assessor was blinded
Incomplete outcome data (attrition bias) All outcomes	High risk	No data for the 8 participants who dropped out
Other bias	High risk	If the cognitive rehabilitation sessions were in addition to standard therapies, the extra intervention may have had the positive effect rather than the content per se
