Fig. 3From: Efficacy of plasma exchange for antineutrophil cytoplasmic antibody-associated systemic vasculitis: a systematic review and meta-analysisForrest plots of the secondary outcomes between the PE and no PE groups. The composite of ESRD or death is shown as a representative of outcomes on renal failure, and SF-36 is shown as a representative of the quality of life indicators. Regarding the timing of outcome measurement, renal failure and relapse are for the overall observational period, and quality of life was at 1 year after the allocation.
