Correlation of ΔDAS28 and ΔMRI synovitis scores with cell marker expression following biologic treatment

	ΔCD3	ΔCD68 sl	ΔCD68 ll	ΔFVIII
ΔDAS28	0.49 (0.025*)	0.27 (0.24)	-0.07 (0.77)	0.244 (0.30)
ΔMRI	0.58 (0.009*)	0.22 (0.378)	0.07 (0.78)	0.33 (0.18)

Correlation coefficient (P =). N = 21 for all IHC groups except FVIII (n = 20) and n = 19 for all MRI groups; ll, lining layer; sl, sublining layer.
