Latent class membership stratified by age at disease onset. Membership in latent class 1 was associated with an increased likelihood for Takayasu’s arteritis. Membership in latent class 2 was associated with an increased likelihood for giant cell arteritis and was more frequent in subjects >60 years at disease onset. Membership in latent class 3 was not associated with an increased likelihood for either Takayasu’s arteritis or giant cell arteritis and comprised the majority of patients with large vessel vasculitis across all age strata.
