  • * RR: age, period, and geographic area RR for each chemical factor compared to no exposure, and RR for LMW exposure adjusted for simultaneous exposure to HMW exposure and vice versa.

  • 95% confidence intervals for the RR.

  • Occupational exposure factors with at least 10 probable exposed cases among men or women workers.
