Table 4 Shoulder function outcome measure scores at recruitment and 6 week follow up (values are mean (SD))

	Recruitment (n = 92)	6 week follow up (n = 81)	difference in points^a	Effect size (Cohen’s d)	Paired t-test
SFInX v1.0 (0–100)	62.1 (23.4)	71.9 (18.9)	10.3 (14.0)	0.44	t(df) = 6.62(80), p < 0.001
DASH (0–100)^b	71.6 (21.1)	77.3 (19.1)	6.8 (11.9)	0.31	t(df) = 5.10(80), p < 0.001
Constant (0–100)	52.2 (20.2)	60.4 (18.3)	9.0 (10.4)	0.44	t(df) = 7.81(80), p < 0.001

^aData from n=81 of whom data from two assessments were available, was used to calculate the difference in points and effect sizes, and used to perform the paired t-test
