Table 5 Internal responsiveness statistics for the PRWE

	Baseline Mean; SD	Follow-up Mean; SD	Observed change¹ Mean; SD (95% confidence interval)	p-value²	SRM
Function (n = 58)	28; 13	14; 11	14; 10 (11-16)	<0.001	1.34
Pain (n = 62)	23; 11	15; 11	8; 9 (6-10)	< 0.001	0.92
PRWE total (n = 58)	52; 22	30; 21	22; 17 (18-27)	< 0.001	1.29
DASH total (n = 53)	47; 21	27; 19	21; 16 (16-25)	< 0.001	1.33

The analysis was performed on patients with an acute wrist injury in whom a change in clinical status between the two measurements was expected.
¹ Observed change in results of questionnaire 1 week after removal of plaster cast or external fixator and 4-5 weeks later.
² p values given for differences between the two measurements described above. Paired samples t-test.
SRM = standardised response mean
