  1. Differences between basic and cardiovascular subgroups in participants with calcification in the area of the carotid arteries. Based on persons, not individual neck-sides.
  2. *Chi-2-test
  3. † We detected no difference in mean age between the persons with (68.4 years SD 4.5) and without (66.8 years SD 5.6) carotid stenosis, p = 0.44 (t-test)
  4. ‡Regular dental - examinations performed in all practices using panorama, e.g. dental and implant treatment.
