Measured outcome scores by symptomatic group

Outcome score	No neck symptoms (n=1297)	Mild neck symptoms (n=154)	Moderate/severe neck symptoms (n=187)	No shoulder symptoms (n=1253)	Mild shoulder symptoms (n=189)	Moderate/severe shoulder symptoms (n=230)
DASH	10.9 (14.9)	22.4 (17.6)*†	31.0 (20.7)* †	9.2 (13.3)	21.3 (16.5)* †	35.2 (19.7)* †
HAQ	1.0 (1.0)	1.7 (1.0)* †	2.0 (0.9)* †	0.9 (1.0)	1.6 (1.0)* †	2.1 (0.9)* †
Grip (kg)	27.5 (11.3)	24.6 (10.6)	23.8 (11.6)	27.5 (11.5)	25.5 (10.3)	24.4 (12.5)
Pinch (kg)	7.6 (7.6)	6.7 (6.1)*	6.6 (7.6)*	7.5 (7.3)	7.1 (7.9)*	6.9 (7.7)*

^*P-value<0.05 compared to no symptoms for this outcome, adjusting for age, BMI, gender, and race (neck/shoulder symptoms were the independent variables while functional scores were the dependent (outcome) variables)

^†P-value<0.05 compared to no symptoms for this outcome, adjusting for age, BMI, gender, race and symptoms at other sites (foot, knee, hip, hand, mid-back, low-back)

For DASH n=1241; HAQ n=1671; pinch and grip n=1461; functional reach n=1505; n for neck symptoms=1638; n for shoulder symptoms=1672
