Comparisons of 7- to 78-joint ultrasonography scores: all different joint combinations show equal response to adalimumab treatment in patients with rheumatoid arthritis

Table 5 Sum power Doppler (PD) scores of the different joint combinations during the study

	Baseline	1 month	3 months	6 monhts	12 months
7-joint score	8.0 (0 to 19)	5.0 (0 to 17)*	3.5 (0 to 13)*	2.0 (0 to 12)**	2.5 (0 to 12)**
12-joint score	9.0 (0 to 42)	8.0 (0 to 31)	6.5 (0 to 26)**	6.0 (0 to 29)*	3.0 (0 to 29)*
28-joint score	10.5 (0 to 50)	8.0 (0 to 34)*	3.5 (0 to 28)**	3.5 (0 to 35)**	4.0 (0 to 35)*
44-joint score	26.5 (1 to 96)	17.0 (0 to 63)**	11.5 (1 to 38)**	12.0 (0 to 63)**	9.5 (0 to 73)**
78-joint score	33.0 (1 to 119)	21.0 (0 to 83)**	15.5 (2 to 52)**	13.5 (0 to 82)**	12.5 (0 to 81)**

Sum PD scores of the different joint combinations at baseline and after 1, 3, 6 and 12 months. All joint combinations showed significant change from baseline (* = P ≤ 0.05, ** = P ≤ 0.001).
