  • *The number of outcomes refers to the g-estimation analysis. There are slightly fewer outcomes because the analyses were restricted to first-time employments up until 1973.

  • †Mortality of lung cancer, violent deaths, respiratory diseases censored.

  • ‡Mortality of myocardial infarctions, lung cancer, violent deaths, respiratory diseases censored.

  • §Lung cancer incidence censored.
