Patient‐Reported Outcomes and Physical Functioning

Assessment	Mean (SD)	n
Brief Pain Inventory—worst pain score
Baseline	5.0 (3.2)	14
Week 48	4.1 (3.1)	13
Week 144	4.1 (2.7)	10
Brief Pain Inventory—pain severity
Baseline	3.9 (2.6)	14
Week 48	3.0 (2.6)	13
Week 144	3.1 (1.9)**	10
Brief Pain Inventory—pain interference
Baseline	4.4 (3.2)	14
Week 48	3.4 (3.4)	13
Week 144	3.3 (2.8)**	10
Global fatigue score
Baseline	5.6 (2.5)	13
Week 24	4.0 (2.6)*	14
Week 48	3.5 (3.0)*	13
Week 144	3.8 (2.2)*	10
SF‐36v2 physical component score
Baseline	32.8 (10.2)	14
Week 24	36.9 (8.6)*	14
Week 48	39.3 (10.3)**	13
Week 144	40.9 (11.8)*	9
Sit‐to‐stand repetitions
Baseline	6.7 (4.2)	10
Week 24	8.4 (4.3)*	10
Week 48	8.5 (4.2)*	10
6MWT, percentage predicted distance walked for age and sex
Baseline	47.5 (30.8)	6
Week 48	51.8 (29.6)	6

6MWT = 6‐minute walk test.

Lower pain and fatigue scores indicate less pain and fatigue; lower SF‐36v2 scores indicate lower functioning.

^* p < .01 and ^** p < .05 based on least squares mean change from baseline using generalized estimating equation model.
