Table 3. APOE genotype of all cases (excluded confirmed pathogenic variants) and controls.

Study size		APOE genotype
		4/4	3/3	2/2	4/3	3/2	4/2	ɛ4 carrier
Controls	93	1	54	2	24	12	0	25
DLB patients	87	3	33	0	45	6	0	49
P-value		0.35	0.0076	0.50	0.0004	0.22	1.0	0.0001

Abbreviation: DLB, dementia with Lewy body.

Comparison between groups (patients n=87, controls n=91) performed by Fisher's exact test. APOE ɛ4 carrier determined by the presence of at least one APOE ɛ4 allele.
