  1. Values are expressed as adjusted odds ratios (95% CI) for participants with complete data. Values are adjusted for personal factors and job stressors with p < 0.2 in univariate analyses using multivariate regression analysis. Ref. = referent. Significant at * p < 0.05, ** p < 0.01. Text in parentheses reflects case groups
  2. a Four levels of response are 1) never, 2) 1–3 days, 3) 1–3 days per week, and 4) every or almost every workday
  3. b For example, body odor, food odor, or perfume
