Correlations [ρ - Rho values (P-values)] between arthroscopic scores and joint effusion, joint circumference percent change and radiographic scores in OC injured MCP joints at week 16.

	Arthroscopy
	Synovium	Cartilage	CDK	Total
Effusion	0.566 (0.006)	0.837 (<0.001)	0.750 (<0.001)	0.802 (<0.001)
JC % change	0.529 (0.011)	0.503 (0.017)	0.467 (0.028)	0.551 (0.008)
R-Enthes	0.297 (0.180)	0.563 (0.006)	0.621 (0.002)	0.459 (0.032)
R-Total	0.665 (0.001)	0.850 (<0.001)	0.815 (<0.001)	0.848 (<0.001)

Bolded ρ values represent statistically significant correlations. JC %=joint circumference percent change from baseline, R=radiograph, Enthes=enthesophyte, CDK=kissing lesion (region from which cartilage sample taken).
