Risk prediction model for mortality in patients with MPA based on BVAS/EUVAS categorization systems. A Cumulative mortality rates in patients with MPA, stratified by risk score. The risk score was defined as the number of risk factors (BVAS ≥20 and a severe EUVAS designation). Short-term (2-year; B), mid-term (4-year; C), and long-term (6-year; D) death-free rates were significantly different among patients with MPA stratified by number of risk factors (P = 0.0002, 0.0009, and 0.0029, respectively)
