Table 3. Linear Model of Glomerular Filtration Rate (ml/min per 1.73 m²)* as a function of Homoarginine.

	Coefficient	95% CI	Beta†	P value
Homoarginine(µmol/L)*	0.404	0.231, 0.577	0.313	<0.001
Homocysteine(µmol/L)	−0.009	−0.014, −0.005	−0.294	<0.001
ADMA (µmol/L)*	−0.595	−1.072, −0.117	−0.169	0.015
L-arginine (µmol/L)*	−0.388	−0.672, −0.104	−0.230	0.008
Presence of diabetes	−0.296	−0.466, −0.126		0.001

Legend: (*) indicates variables that were log-transformed; the regression coefficients estimate the average change in the log values of the response (Glomerular Filtration Rate [GFR] in ml/min per 1.73 m²) per unit change in the predictor (log-unit change [2.72 units on the natural scale µmol/L] if log-transformed); 95% CI indicates 95% Confidence Intervals; Beta^? indicates the standardized regression coefficient (not meaningful for the binary variable diabetes); ADMA: asymmetric dimetyhlarginine; Model R²∶0.289; all variance inflating factors <1.1.
