Univariable and multivariable Cox proportional hazard analyses for the composite end points of renal and overall survival

	Unadjusted			Adjusted model 1a			Adjusted model 2b
	HR	95% CI	P	HR	95% CI	P	HR	95% CI	P
C3 positive	2.01	1.25–3.23	0.004	2.05	1.22–3.45	0.007	2.02	1.20–3.40	0.008

CI, confidence interval; HR, hazard ratio.

^aModel 1: adjusted for age, sex, baseline estimated glomerular filtration rate, serum C3 level, and treatment.

^bModel 2: adjusted for model 1 + % normal glomeruli, % global sclerosis, % cellular crescents, and % interstitial fibrosis and/or tubular atrophy.
