Group		24 hr to 7 d	24 hr to 7 d
Control^a	MCID	0	2
Control^a	MI	1	1
Intervention (BFA)^b	MCID	2	2
Intervention (BFA)^b	MI	4	6

^{^a}

The control group (n = 18) reported 5.6% MI in average and worst VAS pain between baseline and 7 d

^{^b}

The intervention (BFA) group (n = 20) reported 10% MCID in average and worst VAS pain between baseline and 7 d, and 20% and 30% MI in average and worst VAS pain (respectively) at baseline and 7 d.
