  • All-cause mortality models based on 2975 sarin-exposed veterans and 2919 ‘Non-Porton Down veterans’ (reference) over an average 52.2-year follow-up. Cancer incidence models based on 2899 sarin-exposed veterans and 2853 ‘Non-Porton Down veterans’ (reference), over an average 49.8-year follow-up

  • *Adjusted for age, calendar period, branch of service, previous duration of service and place of birth.

  • †Estimates based on 1430 veterans exposed to sarin only (allowing for co-exposure to rubber mixes and mustard sensitivity tests).

  • ‡Estimates based on 1385 veterans exposed to sarin only (allowing for co-exposure to rubber mixes and mustard sensitivity tests).

  • §Excludes 47 veterans with missing state data.
