a
Values are mean ± SD (n). RSMI, relative skeletal muscle index; BFM, body fat mass; nbLBM, non-bone lean body mass; FFMI, fat free mass index; VAT, visceral adipose tissue; WC, waist circumference; HC, hip circumference; wbBT, whole body bone tissue.
b
P value within arms; change from baseline to pre-surgery.
c
P value between arms; change from baseline to pre-surgery.
d
P value < 0.05 from baseline value; all other net changes were not significant.
