Time point	No (%) of patients		Raw risk difference (95% CI)	P value*
	Physiotherapy	Usual care
Baseline	0/253 (0)	0/250 (0)	—	—
1 month	26/239 (11)	34/239 (14)	−3% (−9% to 3%)	0.27
3 months	98/229 (43)	79/214 (37)	6% (−3% to 15%)	0.26†
6 months	118/208 (57)	120/195 (62)	−5% (−14% to 5%)	0.26†

*P value based on Mantel-Haenszel test stratified by quarter of FAOS at baseline.

†Rounded to 0.26 by coincidence, with difference in their third decimal confirmed.
