Results of hierarchical multiple regression analyses. For the model, the total adjusted R² was 95.1%

Variable	Coefficient	Std error	t	Individual contribution to R² (%)
√Physician global VAS	0.180	0.008	23.6	7.7
√Patient global VAS	0.159	0.007	21.3	6.3
LN (Dactylitis count+1)	0.377	0.037	10.2	1.4

LN (CRP+1)	0.102	0.012	8.3	1.0
LN (Swollen joint count+1)	0.101	0.018	5.5	0.4
√SF36−PCS	−0.253	0.018	−14.3	2.8
√SF36−MCS	0.014	0.016	0.8	<0.1
LN (Tender joint count+1)	0.048	0.016	2.9	0.1

All t values were significant, apart from SF-36 MCS.
CRP, C-reactive protein (mg/l); LN, log normal; MCS, mental component scale of SF36; PCS, physical component scale of SF36; VAS, visual analog score (100 mm).
