  1. aNumber of participants with exposure estimated by an industrial hygienist. All other study participants are assigned zero exposure.
  2. bMean (and standard deviation) of lifetime cumulative exposure in gram-years (g-years) for participants with estimated exposure. Cumulative exposure is calculated as 1,000 times the product of intensity (mg/hr) by decade, number of hours per day (hr/day), number of days per year (days/yr), and years by decade, and then summed across all decades.
  3. cOdds ratio (and 95 % confidence intervals) of lifetime cumulative exposure (per 1 g for arsenical and dinitroaniline, or per 10 g for all others based on median exposure), adjusted for matching variables (10-year age group, sex) and for age, and education.
  4. *p < 0.05.
