Distribution of ACE I/D gene polymorphism in early and late onset patients

Category	DD	ID	II	D	I	Comparison of groups	OR(95 % CI)	p-value
	N (%)	N (%)	N (%)
Early onset (130)	63(48)	48 (37)	19 (15)	0.65	0.35	D vs I	2.011	0.015*
Late onset (129)	37 (27)	49(38)	43 (33)	0.48	0.52	DD vs ID + II	1.81	0.022*
						ID vs DD + II	1.27	0.358
						II vs DD + ID	0.336	0.0004*

OR for genotype was calculated with DD vs ID, II and ID vs II. OR for allele was calculated with D vs I
