Group A	29.9 (2.0)	0.7 (2)	0.5 (1.6)
Group B	30.3 (2.7)	0.9 (2)	0.6 (1.9)

^aThigh girth: circumference at the thigh, 10 cm proximal portion form the top of the patella.

^bCalf girth: the maximum circumference of the calf.

^†Preoperative increment: increment of the circumference compared with that of the pre-operation.

*Statistically significant difference between the two groups: p <0.05.
