International Registry of Acute Aortic Dissections

The International Registry of Acute Aortic Dissections (IRAD) is a consortium of research centers that are evaluating the current management and outcomes of acute aortic dissection.

This website was developed for MCORRP at the University of Michigan.

It boasts an impressive 300+ field CCK content type, split into multiple pages with the help of the Multistep module, and using massive amounts of conditional field validation. All in Drupal 5 magic.

update: The internal team has been working on some major improvements as of 2010, and will soon be upgraded to Drupal 6 with awesome new features.
