Table 2.

“Inflammation” and “damage” US scores for each enthesis according to the presence or absence of juxta-articular joint tenderness. Scores are the mean (median, IQR).

	Inflammation index at associated enthesis		Damage index at associated enthesis
	Tender	Nontender	Tender	Nontender
EJR	1.9 (2,2.8)	0.8 (0,2.0)*	0.9 (1,2.0)	0.5 (0,1.0)*
EJL	1.0 (1,2.0)	0.7 (0,1.3)	0.7 (1,1.0)	0.5 (0,1.0)
KJR	2.3 (3,2.5)	1.3 (1,2.0)*	0.8 (1,0.8)	0.5 (1,1.0)
KJL	1.5 (2,3.0)	1.7 (2,3.0)	0.7 (1,1.0)	0.8 (1,0.3)
AJR	1.0 (1,2.0)	0.8 (0,2.0)	0.4 (0,0.8)	0.5 (0,1.0)
AJL	1.0 (0,2.0)	0.8 (0,1.5)	0.5 (0,1.5)	0.4 (0,1.0)

*Comparison of tender versus nontender: denotes P < .05 using Mann-Whitney U-test.
