TL;DR: Criteria for the classification of Churg-Strauss syndrome were developed by comparing 20 patients who had this diagnosis with 787 control patients with other forms of vasculitis, and advantages of the traditional format compared with the classification tree format are discussed.
Journal ArticleDOI
