Associations between the different markers of disease severity

	GFR		ERBF		TRV
	R	P	R	P	R	P
ERBF	0.94	<0.001	–	–
TRV	−0.42	<0.001	−0.30	0.002	–	–
UAE	−0.20	0.04	−0.15	0.1	0.47	<0.001

Depicted values are Pearson correlation coefficients and P values. Variables are log-transformed in case of non-normal distribution (TRV, UAE).
