Table 4 Univariate and multivariate analyses of the association of wheezing over the past 12 months with intestinal helminthic infections, anti-A. lumbricoides IgE antibodies and diarrhoea in 148 non-atopic children

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
