Comparison of physical functions at baseline and week 4 between the groups.

Physical functions	TOLF-HF group (n = 29), mean (SD)	Control group (n = 31), mean (SD)	t/F	P value
Baseline*	20.38 (10.42)	21.68 (9.44)	−0.506	0.614
Week 4†	9.93 (5.35)	16.55 (8.10)	13.792	<0.001

SD, standard deviation.

^*The data were compared by the independent sample t-test.

^† The data were compared by analysis of covariance (ANCOVA) after controlling for the pre-intervention physical functioning values and the number of co-morbidities.
