Computable phenotype for real-world, data-driven retrospective identification of relapse in ANCA-associated vasculitis
Objective ANCA-associated vasculitis (AAV) is a relapsing-remitting disease, resulting in incremental tissue injury.The gold-standard relapse definition (Birmingham Vasculitis Activity Score, BVAS>0) is often missing or inaccurate in registry MOSFETs settings, leading to errors in ascertainment of this key outcome.We sought to create a computabl
