Survival curves of patients with MPA based on BVAS/EUVAS categorization systems. A The survival rates over the entire follow-up period were significantly lower in patients with BVAS ≥ 20 than in those with <20 (P = 0.003). B The survival rates over the entire follow-up period were significantly lower in patients with severe EUVAS than in those with non-severe EUVAS (P = 0.020). Survival rates were calculated using the Kaplan–Meier method and compared using the log-rank test
