  1. BDI, Beck Depression Inventory version; BMI, Body mass index; LVEF, Left ventricular ejection fraction; MI, Myocardial infarction.
  2. *Means of age, BDI-scores and BMI, percentages otherwise of original data. Differences in baseline characteristics with respect to Meijer et al. [11] are due to the fact we included 377 patients more as we used imputation of missing values for depression.
  3. †Elevated depression score as assessed by structured diagnostic interviews and standard cut-off values on self-report questionnaires.
  4. ‡Mean BDI-1A scores for subjects in highest, intermediate and lowest quartile of depression z-scores for n = 6,423 subjects in which BDI-1A scores were measured.
