  1. I intervention group, C control group, FMD flow-mediated dilation, cIMT carotid intima-media thickness, BP blood pressure
  2. aBaseline and 8-weeks values are unadjusted mean (SD)
  3. bChange scores and 95 % CIs are the differences between groups (relative to control) after adjustment by ANCOVA for the baseline value. Triglycerides ANCOVA additionally adjusted for marital status, time at current workplace and job category
  4. cValues denote the severity of discomfort or pain from 0 (No discomfort) to 10 (Extremely uncomfortable)
  5. *Significant (p = 0.049)
