Always indicates number of subjects in each category, unless otherwise noted.
‡
Some pans counted in both categories, i.e., metal and non-stick, if information available.
Study-participant survey reponses (n = 21) related to life-style and housing conditions, significance was defined as p ≤ 0.05. Significance was assessed using unpaired t-tests (exacerbators vs. non-exacerbators). Bold font indicates significance (*), defined as p ≤ 0.05 and italicized font indicates a trend (p < 0.15).
