Data represent mean ± SD (range). Numbers in bold are significantly different between the pre- and post-T&A conditions.

HDL = high-density lipoprotein; HOMA-IR = homeostasis model assessment of insulin resistance; LDL = low-density lipoprotein; TChol = total cholesterol; TG = triglycerides. See Table 1 legend for expansion of other abbreviations.
