Longitudinal analysis found no evidence that the difference between the ω-3 LCPUFA and control groups in the risk of ‘any’ IgE mediated allergic disease or ‘individual IgE mediated allergic disease symptoms (eczema, rhinitis, rhino-conjunctivitis or wheeze)’ changed over time (group by time interaction p-values > 0.05). Here, IGHE is linked to allergic disease.
