Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Description of randomisation unclear ('using random numbering')
Allocation concealment (selection bias)	Unclear risk	No mention of randomisation being carried out independently
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No information about blinding
Incomplete outcome data (attrition bias) All outcomes	High risk	No attrition from intervention group; 34% attrition from control group
Selective reporting (reporting bias)	Low risk	All outcome measures mentioned in methods were reported.
Other bias ‐ training and supervision	Low risk	"Implementation and management of the cognitive intervention program were carried out by two skilled and professionally educated occupational therapists."
Other bias ‐ treatment manual	Low risk	Clear structure for the intervention
