Analysis of threshold effects

	eGFR (mL/minute/1.73 m2)	ACR (mg/g)
Standard linear regression model	1.08 (1.00, 1.15) 0.044	1.22(1.14, 1.30) < 0.001
Two-stage regression models
Inflection point (K)	1.86	3.09
< K	1.37 (1.15, 1.64) < 0.001	1.52(1.37, 1.68) < 0.001
> K	0.99 (0.90, 1.08) 0.771	0.96(0.86, 1.07) 0.445
log-likelihood ratio test	0.003	< 0.001

The adjustment strategy is the same as the fully adjusted regression model
