Linear regressions are used to investigate the associations in three models. Model 1(adjustment for age, race/ethnicity, and visceral adipose tissue), model 2(adjustment for model 1 + SHBG, CRP, physical activity, sedentary behavior, cigarette smoking, alcohol use and time from baseline to CT), model 3 (adjustment for model 2 + hypertension, diabetes mellitus, dyslipidemia, cholesterol medication, thyroid agents), SHBG (sex-hormone binding globulin), CRP (C-reactive protein), fT (free testosterone).
