The reported IRR corresponds to the history of maternal atopy by specific IgE levels (exposed group) and the reference category corresponds to no history of maternal atopy. IRR = incidence rate ratios for symptoms (a measure of relative risk). See Figure 1 legend for expansion of other abbreviation.
