The cumulative risk of all‐cause death within a 3‐year period for an individual patient with pulmonary involvement in ANCA‐associated vasculitis (AAV) can be computed using the following formula:Pattimet3year=1–0.9956803expPI,where the PI = 0.3335 × Age/5 + 1.7548 × Tumors − 0.4383 × Hb/10–0.3799 × FVC% pred/10. Here, GSTM1 is linked to anti-neutrophil cytoplasmic antibody-associated vasculitis.
