Independent predictors of the GFR slope in the multivariate regression model

Variables	β	SD	t	P Value	R2
Baseline eGFR	−0.025	0.071	−2.26	0.03	0.67, F: 31.38, P<0.001
Body mass index	−0.121	0.095	−2.84	0.03
Smoking	−0.194	0.001	−1.99	0.05
Age	−0.029	0.004	−2.45	0.03
Time-averaged proteinuria	−1.296	0.011	−10.95	<0.001
C4d+	−1.016	0.313	−4.76	0.003

Baseline eGFR is in milliliters per minute per 1.73 m², body mass index is in grams per meter², smoking is yes or no, age is per year, time-averaged proteinuria is in grams per gram, C4d positive is versus C4d negative, and β indicates β error.
