  • *Adjusted for age, sex, and length of period between phase 1 and 3; baseline cases at phase 1 were excluded.

  • †Group scores of job control (1, 2, 3) were modelled as one (ordinal) variable; odds ratio reflects increase in odds of new coronary heart disease per unit increase in this variable.
