Dementia risk scores used as surrogate outcomes in multidomain prevention trials

Study	Trial	Dementia risk score	Outcome type	Main results
O’Donnell et al., 2015 [39]	In-MINDD	LIBRA	Primary	Participants in both arms of the trial showed a small improvement in their LIBRA score. The improvement was slightly larger in the intervention arm, but not statistically significant after 6 months.
Solomon et al., 2018 [40]	FINGER	CAIDE	Post hoc	The intervention had a significant impact on lowering the CAIDE risk score after 2 years.
Barbera et al., 2020 [41]	FINGER MAPT preDIVA	CAIDE	Post hoc, individual participants pooled analysis	CAIDE score decreased significantly as a result of the interventions after 2 years.
Coley et al., 2020 [42]	preDIVA MAPT HATICE	LIBRA and CAIDE	Post hoc, each trial analyzed separately	CAIDE and LIBRA scores showed statistically significant between-group differences after multidomain interventions after 1.5 to 2 years.
Deckers et al., 2020 [29]	FINGER	LIBRA	Post hoc	The intervention decreased dementia risk as indicated by decreasing LIBRA score after 2 years.
McMaster et al., 2020 [23]	Body Brain Life	ANU-ADRI	Primary	Significant reduction in ANU-ADRI score for BBL compared with control after 2 months.
