  1. Columns show two multivariable models for each measure of endothelium-dependent microvascular function: one with the effort-reward ratio and the other with the overcommitment scale. Note that the effort-reward ratio and the overcommitment scale were not mutually adjusted, which explains the empty cells in their respective columns. Values given are unstandardized beta-coefficients with 95% confidence interval
  2. MBF myocardial blood flow
  3. Significance level: *** p < .001, ** p < .010, * p < .050
