Clinical and laboratory characteristics of 290 AD-affected children divided into two groups on the basis of the work-up for FA

AD-affected children 290	FA–AD-affected children 88 (30.3%)	Not FA–AD-affected children 202 (69.7%)	p

Hp infection rate (%) 11 (36.6%)	2 (50%)	9 (34.6%)

AD: atopic dermatitis; FA: food allergy.

p-values are expressed only for significant results (<0.05).

1/OR: inverse odds ratio; the test was considered significant when a 95% confidence interval excluded unity.
