Vitamin d levels checked for clues to heart risk in kidney patients
NCT ID NCT07200804
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether vitamin D levels in the blood are related to early signs of artery hardening (atherosclerosis) in people on dialysis. Researchers measured vitamin D and used ultrasound to check artery thickness in 90 adults with kidney failure. The goal was to see if a link exists, not to test a treatment.
