  1. The data are expressed as B coefficient (95 % confidence interval)
  2. T, testosterone; E2, estradiol; SHBG, sex hormone binding globulin
  3. Model 1 was unadjusted. Model 2 included terms for age, residence area, economic status and current smoker. Model 3 included terms for model 2, BMI, log (HOMA-IR), diabetes and systolic pressure. To obtain the average percentage change in free T, SHBG, LH or FSH from log hormone = 100 × (exp(B coefficient) - 1)
  4. *P < 0.05, **P < 0.01, ***P < 0.001. Linear regression analysis was used
