Table 3 Comparison of exceedance proportions of the screening criteria for environmental hypersensitivity/intolerance between the four groups

From: Comparison of environmental intolerances and symptoms between patients with multiple chemical sensitivity, subjects with self-reported electromagnetic hypersensitivity, patients with bronchial asthma, and the general population
