Cardiovascular health score, social network size, and all-cause mortality in a Korean prospective cohort
- Prospective cohort study
Authors' conclusion
Higher CVH and larger networks were independently associated with lower all-cause mortality in middle-aged Korean adults.

- Participants
- 11,312 adults
- Exposure
- Cardiovascular health (CVH) score tertiles and social network size categories
- Outcome
- All-cause mortality
- Follow-up
