Results of subgroup analysis of TUG, VAS, and BBS (length of follow-up).

Measurements	Number of included articles	Subgroup	I2 value (%)	WMD (95% CI)	P value
TUG	3	≤12 wk	93.4	−1.39 (−3.52, 0.73)	.199
	3	˃12 wk	35.7	−0.37 (−0.78, 0.05)	.082
VAS	3	≤12 wk	66.3	0.06 (−1.49, 1.62)	.935
	2	˃12 wk	43.9	−1.02 (−2.21, 0.17)	.094
BBS	3	≤12 wk	0	0.95 (−0.20, 2.11)	.104
	3	˃12 wk	26.6	1.40 (0.45, 2.34)	.004

Bold values in the tables indicate meaningful results with P < 0.05.

BBS = Berg balance scale, TUG = timed up and go test, VAS = visual analogue scale.
