Age- and time-dependent increases in incident anti-glomerular basement membrane disease: a nationwide cohort study.

Background: Epidemiologic assessments of anti-glomerular basement membrane (GBM) disease have been challenging due to its rare occurrence. We examined changes in the incidence and outcomes from 1998 to 2018 using nationwide healthcare registries.

Methods: All patients with incident anti-GBM disease were identified using the International Classification of Diseases, 10th Revision code DM31.
