To compare temporal artery biopsy (TAB)-positive giant cell arteritis (GCA) to TAB-negative GCA and patients with GCA mimics METHODS: PATIENTS DIAGNOSED WITH TAB-POSITIVE AND TAB-NEGATIVE GCA BETWEEN 1/1/1998 AND 12/31/2013 WERE: retrospectively identified. These two groups were compared to a cohort of patients with TAB performed between 1/1/2009 and 12/31/2010 in which the TAB was negative and alternative diagnosis was provided after a minimum of 6-months of follow-up. Baseline characteristics were compared between groups using chi-square and rank sum tests.
