Data presented are the arithmetic mean (SD) at baseline and 24 months.

Changes from baseline are the arithmetic difference with 95% confidence intervals, unless otherwise indicated.

Bonferroni-adjusted P values are for the difference from baseline to 24 months within the group.

GH and IGF-I data were transformed to the natural logarithmic scale before conducting the statistical analyses; results are reported as the ratio of geometric means (fold-changes from baseline) with upper and lower 95% confidence intervals.

FFM measured by 4-compartment (4-C) model and by DXA

AVF and ASCF areas from single-slice abdominal CT scan

Quicki Index is insulin sensitivity estimated from fasting glucose and insulin.

Abbreviations: GH = growth hormone; IGF-I = insulin-like growth factor-I; FFM = fat-free mass; TFM = total fat mass; AVF = abdominal visceral fat; ASCF = abdominal subcutaneous fat; FBG = fasting blood glucose; LDL = low density lipoprotein; HDL = high density lipoprotein
