Risk factors associated with the composite outcome of ESKD or vasculitis-related death at the end of the first year after pauci-immune glomerulonephritis diagnosis

Low serum C3, mg/dl	6.47 (1.47–28.35)	0.013
Oliguria, present versus absent	29.57 (4.74–184)	<0.0001
Chronicity score	1.77 (1.23–2.54)	0.002
Serum creatinine, mg/dl	0.82 (0.57–1.19)	0.3
Estimated GFR >30 ml/min per 1.73 m2	0.08 (0.0001–52.1)	0.44
Normal glomeruli >10%	1.22 (0.13–3.13)	0.59
Activity score	1.37 (0.85–2.24)	0.19
Acute dialysis requirement	0.85 (0.12–5.81)	0.87

Data are hazard ratio (95% confidence interval) and are based on a multivariate model for first-year outcome.

ESKD, end-stage kidney disease; GFR, glomerular filtration rate.
