Table 5 Univariate and multivariate analyses of the association of atopy with gender, age, intestinal helminthic infections, and diarrhoea in the subpopulation tested for serum anti-allergen IgE antibodies

From: The presence of serum anti-Ascaris lumbricoides IgE antibodies and of Trichuris trichiura infection are risk factors for wheezing and/or atopy in preschool-aged Brazilian children
