Multivariate linear mixed models effects of uPCR with biomarkers

	Estimate SE	p Value
Intercept	1.4±1.2	0.228
EC4d (log net MFI)	0.8±0.2	<0.001
ECR1 (log net MFI)	−0.6±0.2	0.019
C3 (mg/dL)	−0.01±0.01	0.280
C4 (mg/dL)	−0.01±0.03	0.686

Intercept and estimates for each of the marker with p values are given. For example, a one-unit decrease in log EC4d was associated with a 0.8±0.2-unit decrease in uPCR, while a one-unit increase in log ECR1 was associated with a 0.6±0.2-unit decrease in uPCR. C3 and C4 levels were not associated with the change in uPCR after adjusting for EC4d and ECR1 levels.

MFI, mean fluorescent intensity; uPCR, urinary protein to creatinine ratio.
