Notes

  • (a) Figures are shown in light type if they are based on fewer than 10 actual cases.
  • (b) Comparisons of rates based on OPRA reports are likely to be misleading because workers in some occupations are much more likely to have access to occupational physicians than those in others.
  • (c) Some physicians report on a sample basis, for one month in each year. Estimated totals for these are calculated by multiplying the actual number of cases reported by 12.
  • (d) Some diagnoses have more than one causative substance reported.
  • (e) Since some diagnoses have more than one substance reported, percentages do not sum to 100.
  • "-" means zero or number rounds to zero.
  • (p) Provisional.
