NCT00628329 · Status: WITHDRAWN · Type: OBSERVATIONAL
Last updated 2012-05-07
Summary
We wish to understand the association of Vitamin A serum levels and Vitamin A receptor number and responsiveness in asthmatics. We believe that Vitamin A receptors may be less prevalent in asthmatics and their responsiveness decreased.
