Group characteristics of the high‐risk (APOE‐ε4 carriers) and low‐risk groups in the sample

	Whole sample	APOE4− group	APOE4+ group	p
Number of subjects	261	185 (71%)	76 (29%)
Male/female	110/151	78/107	32/44	0.993
Age mean/SD	56.6/6.7	57.0/6.8	55.6/6.6	0.065
MMSE mean/SD	29.1/0.8	29.0/0.7	29.1/0.8	0.219
15OT score mean/SD	13.1/1.78	13.0/1.86	13.5/1.51	0.025*
Framingham CV risk	6.46/6.17	6.41/6.16	6.61/6.27	0.660
NGMV mean/SD	0.452/0.019	0.452/0.019	0.453/0.020	0.761

The groups did not differ significantly for gender and age distributions (p = 0.993 and p = 0.065, respectively). The APOE4+ groups did not differ in mean MMSE scores (p = 0.219). The APOE4+ risk group scored higher on the 15‐object test (15OT, p = 0.025). The groups did not differ significantly in cardiovascular risk scores and NGMV (p = 0.660 and p = 0.761, respectively). Significant differences are marked with *.
