Association of baseline serum albumin (per 0.1 g/L higher) with 54-week eGFR change

	n	eGFR Change (95% CI)	P
All completers	52	0.9 (0.5, 1.4)	<0.001
Placebo arm	21	0.4 (−0.2, 1.1)	0.21
Pirfenidone at 1200 mg/d	17	1.1 (0.0, 2.2)	0.06
Pirfenidone at 2400 mg/d	14	0.9 (0.1, 1.7)	0.03

Shown is the association of baseline serum albumin with change in eGFR over the 54-week period using linear regression. Positive values indicate that a higher serum albumin level was associated with improvement in eGFR during the course of the study.
