NCT ID NCT04777383
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how tiny blood vessels in the skin of healthy volunteers respond to substances that make them widen or narrow. Researchers used a mild electrical current to deliver these substances through the skin and measured changes in blood flow with light. The goal was to better understand blood vessel function and find ways to detect early signs of diseases like diabetes or heart problems.
