  • Models were multivariable adjusted for age, race, gender, clinic location, education, body mass index, smoking, alcohol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, diabetes, hypertension, coronary heart disease (CHD), congestive heart failure, stroke and antidepressant medication use.

  • All p<0.05 for log HR of depression except for results in non-white column (p range 0.16–0.24).

  • * Population size with coronary heart disease shown is at study entry and changes over time as it was modelled as time-varying.

  • Categorical variables.

  • Continuous variable.
