Comparison of responsiveness of the Brief MHQ score and objective function measures, controlling for disease type.^*††

	Baseline value	Follow-up value	p value♣	SRM†
Brief MHQ Score	58.8 ± 14.4	70.5 ± 11.5	0.001	4.15
Original MHQ Score	59.7 ± 13.6	70.9 ± 10.2	0.001	3.30
Grip Strength (kg)	10.7 ± 3.3	11.6 ± 5.7	0.001	0.36
Pinch Strength (kg)	5.3 ± 1.7	14.1 ± 3.75	0.001	1.60
Jebsen-Taylor Test score (sec)	40.6 ± 8.57	44.2 ± 11.45	0.001	1.26

^*Cell values are mean ±SD.

^♣Paired t-test comparing follow up scores and baseline scores.

^†Standardized Response Mean is calculated using the following formula: (follow-up mean − baseline mean)/standard deviation of the change

^††Excluding patients with carpal tunnel syndrome, and RA patients who did not undergo SMPA arthroplasty. Patients who did not have both baseline and follow-up measurements were also excluded from analysis
