Abbreviations: BMI body mass index, SBP systolic blood pressure, DBP diastolic blood pressure, HOMA-IR homeostasis model assessment of insulin resistance, LDL low-density lipoprotein, HDL high-density lipoprotein, hs-CRP high-sensitivity C-reactive protein, e-GFR estimated glomerular filtration rate, LBM lean body mass SM skeletal muscle mass, BMC bone mineral content, DM diabetes mellitus, CVA cerebrovascular accident, MI myocardial infarction. All values are means ± SDs or n (%). p-values were calculated by Student’s t-test or Chi-square test. Adiponectin, insulin, HDL, TG and HOMA-IR were log transformed because they were not normally distributed. The data describing comorbidities and treatments were obtained from structured questionnaires.
