RCT: Among patients with ANCA-associated vasculitis without severe glomerulonephritis or alveolar hemorrhage treated with Rituximab, a reduced-dose glucocorticoids regimen (prednisolone 0.5 mg/kg/d) was noninferior to a high-dose glucocorticoid regimen (prednisolone 1 mg/kg/d) for the induction of disease remission.
