Figure 2. Survival curves of patients with ABRA, CAA, and PCNSV.

Survival of the patients with CAA was significantly reduced compared to patients with ABRA (p = 0.008). Significance remained after adjustment for age at diagnosis. The differences in survival between the patients who had ABRA and those with PCNSV were not statistically significant, univariately or after adjustment for age. ABRA = amyloid-β–related angiitis; CAA = cerebral amyloid angiopathy; PCNSV = primary CNS vasculitis.
