Spearman correlations between Urine oxalate measures and eGFR at last follow-up, among patients with at least 1 stone event in their lifetimes (N=62)

Laboratory Characteristic*		eGFR at last follow-up†
Urine Oxalate (1.73m2/24hr)	N	27
	r	0.02
	P	0.91
Urine Oxalate concentration	N	27
	r	−0.22
	P	0.26

The r statistics denotes spearman rank coefficients. P-values in bold indicate statistical significance at the 0.05 alpha level.

^*Laboratory measure is median value across the patient's lifetime unless otherwise specified.

^†eGFR labs were obtained when patients were 15 years of age or older.
