Odds ratios (95% confidence intervals)* of newly reported coronary heart disease at phase 3 by average self reported job control at phase 1 and 2† in total sample (men and women combined) adjusted for age, sex, and length of period between phase 1 and phase 3 (model I), and separately adjusted for employment grade (model II), negative affectivity (model III), and coronary risk factors (model IV)

  • *Cases of coronary heart disease at phase 1 and 2 were excluded.

  • †Sum of continuous job control scales at phase 1 and 2, with resulting score divided into thirds.

  • ‡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.
