  • Variables in multivariate analysis include time to death, time to start or restart of renal replacement therapy, and relapse as time-dependent variables. Other covariates are age, sex, ANCA specificity, dialysis at diagnosis, nonrenal relapse, hypertension, and proteinuria and eGFR at 6 months.
