Groups2
Group 2 names the comparator: control.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Intervention | Intervention: Pictorial information about carotid ultrasound results to the participant and his/her primary care physician. Asymptomatic atherosclerosis presented as vascular age with a gauge going from green (biological age 10 years younger than chronological age), over yellow, orange to red (10 years older). Plaque formation shown as a traffic light with a green dot (no plaque) or red dot (plaque) for each side. General information about atherosclerosis as a dynamic modifiable process and recommendation to follow clinical guidelines for risk factor control. After 2-4 weeks a follow-up call by a research nurse, to give additional information and reassurance, if needed. Identical information to the study participant is sent by post after 6 months.~CVD risk factors are managed according to clinical guidelines within primary health care during the entire study period. | 5 | 1,749 | EG000 |
| Group 2 | Control | The comaparator is that the study person and his/her physician do not get any information about carotid ultrasound results on silent atherosclerosis. They are only informed about results of measured conventional CVD risk factors CVD risk factors are managed according to clinical guidelines within primary health care during the entire study period. | 2 | 1,783 | EG001 |
