Cross-sectional association of widespread cartilage damage^* and maximum synovitis scores from the whole knee.

Presence of Cartilage Damage	Adjusted*** OR (95% CI) for CEMRI Max Synovitis Score†
	All Subjects, n = 342	Excluding Subjects Taking Antiinflammatory Drugs, n = 285	Excluding Subjects with Chondrocalcinosis on Radiography, n = 312
< 4 Subregions*	1.00 (reference)	1.00 (reference)	1.00 (reference)
≥ 4 Subregions	1.91 (1.24, 2.92)	1.65 (1.03, 2.63)	1.95 (1.26, 3.02)
< 6 Subregions**	1.00 (reference)	1.00 (reference)	1.00 (reference)
≥ 6 Subregions	1.94 (1.27, 2.74)	1.67 (1.05, 2.63)	1.89 (1.22, 2.93)

^*Knees with 4 or more subregions with cartilage score of 2 or above were considered to have widespread cartilage damage.

^**Knees with 6 or more subregions with cartilage score of 2 or above were considered to have widespread cartilage damage.

^***Adjustment made for age, sex, and body mass index.

^†Synovitis score ≥ 1 in at least 1 of 11 sites.
