TABLE 6.

Unadjusted odds ratio for stool anti-CRD IgA-positive children versus stool anti-CRD IgA-negative children after 4.2 years by major histocompatibility complex class II DQB1 or DRB1 allele^a

Class II allele	Odds ratio	95% CI	P value
DQB1*0202	2.73	0.60, 12.4	0.19
DQB1*0301	0.70	0.23, 2.12	0.53
DQB1*0503	1.65	0.36, 7.58	0.52
DQB1*0601	0.73	0.27, 2.00	0.55
DRB1*0701	0.96	0.34, 2.72	0.93
DRB1*1501	0.77	0.28, 2.11	0.61

^aUnivariate logistic regression analysis of ever being IgA positive after 4.2 years of follow-up. Only those MHC class II alleles with a frequency of ≥10% were assessed in the regression models.
