Table 5. – Comparison of the osteoprotegerin level according to the albuminuria and GFR classifications.

	OPG	p
Albuminuria (mg/dL)		0.126**
Stage 1	19.8 (15.4- 23.7)
Stage 2	21.0 (18.6 – 30.6)
Stage 3	28.8 (21.9 – 29.7)
Classification of renal dysfunction (ml/min/1.73m²)		< 0.001**
Stage 1	18.8 (16.8-21.2)^a
Stage 2	18.6 (15.7-20.7)^a
Stage 3a	23.7 (20.9-30.7)^b
Stage 3b	27.4 (21.8-29.3)^b
Classification of renal dysfunction (ml/min/1.73m²)		< 0.001*
Stage 1 and 2	18.1 (13.8 – 21.0)
Stage 3a and 3b	23.8 (20.7 – 30.1)

GFR: glomerular filtration rate; OPG: osteoprotegerin. *Mann-Whitney; **Kruskal-Wallis with Dunn posthoc test. Same letters - no statistical difference and different letters – with statistical difference.
