Table 3.

Spearman correlations between the 1-year recall modified DASH-W change scores and the self-reported work ability, work productivity, and symptom severity change scores (n=551)

Scale	r	p
Work ability change ^a	0.47	<0.0001
Work productivity change ^a	0.44	<0.0001
Symptom severity change ^a	0.36	<0.0001

Abbreviations: DASH-W, Disabilities of the Arm, Shoulder, and Hand, Work module.

If subjects reported symptoms in more than one region of the upper extremity, the maximum change on each measure (work ability, work productivity, symptom severity) was used for comparison to change in 1-year recall modified DASH-W scores.
