Study summary

Hypertension is an underdiagnosed and undertreated disease in real-life. Blood pressure and kidney functions are known to be closely related. Increased serum level of Cystatin C, a sensitive biomarker for renal function, seems to predict adverse cardiovascular events. The investigators aimed to evaluate the predictive value of serum Cystatin C for control of hypertension in a community-based study.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 27, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
