^#: a total of 147 workers participated in the survey, 135 of these were tested for immunoglobulin (Ig)E and 132 had skin prick testing, thus n<147 for some analyses due to missing data for some characteristics; ^¶: these outcomes were not associated with other potential explanatory variables in unadjusted analyses (race/ethnicity, sex, age, smoking status, history of ever working as a contractor, positive reaction on skin prick test to other tested extracts, elevated total IgE, soy-specific IgG, peanut- specific IgE, storage mite-specific IgE, inhalable dust exposure category and inhalable soy antigen exposure category); ⁺: unadjusted odds ratio and 95% likelihood ratio confidence intervals; ^§: self-reported. ^ƒ: referent.
