Distribution of CagA status among the three study groups.

	Autoimmune diabetes		Nonautoimmune diabetes
	Type 1	LADA	Type 2
	(n = 105)	(n = 234)	(n = 156)
Hp negative	58 (55%)	112 (48%)	80 (51%)
Hp positive, CagA negative	26 (25%)	73 (31%)	57 (37%)
Hp positive, CagA positive	21 (20%)	49 (21%)	19 (12%)
CagA prevalence in Hp positive patients	45%	40%	25%

Hp positive, autoimmune versus nonautoimmune diabetes: χ ² = 0.0055; p = 0.815.

CagA positive, autoimmune versus nonautoimmune diabetes: χ ² = 1.556; p = 0.212.

CagA positive/Hp positive, type 1 versus type 2 diabetes: χ ² = 5.125; p = 0.024.

CagA positive/Hp positive, LADA versus type 2 diabetes: χ ² = 4.775; p = 0.028.
