HypertensionCohort study
Association of long-term time in target range for systolic blood pressure with cardiovascular risk in the elderly: a Chinese veteran cohort study
- Prospective cohort study
Authors' conclusion
Greater long-term TTR for SBP was associated with a decreased risk of CV events in elderly individuals independent of mean BP
Study context
- Population

- Participants
- 943 veterans
- Exposure
- Highest vs lowest quartile of SBP time in target range
- Outcome
- First occurrence of CV events during annual visits
- Follow-up
- 15 years
