  • 4-150 0=Unexposed, 1=exposed; first factor:second factor. OR (95% CI) adjusted for variables according to tables 2, 3. The reference group (RR=1) refers to cases and referents among the workers unexposed to both factors (0:0).

  • 4-151 Synergy index (95% CI) 1=no interaction; 2=an effect among those with combined exposure twice what would be expected from additivity of effects.
