NCT ID NCT04587323
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study measured specific blood proteins in 75 adults with COVID-19 to see if they are linked to severe outcomes like ICU admission, breathing support, or organ failure. Researchers analyzed stored blood samples to look at markers that affect blood vessel health. The goal was to better understand why some people get much sicker than others.
