Figure 4. Predicted morning free testosterone (T) as a function of morning luteinizing hormone (LH) and fasting insulin concentrations in obese peripubertal girls.

Figure 4

A. Predicted free T as a function of morning LH concentration, with insulin, age, and BMI z-score held fixed at median values of 157 pmol/liter (21.9 μIU/ml), 12.4 years, and 2.4, respectively. The dashed lines enclose the 95% confidence band for the regression line. B. Predicted free T as a function of fasting insulin concentration, with LH, age, and BMI z-score held fixed at 2.9 IU/liter, 12.4 years, and 2.4, respectively. C. Predicted free T as a function of morning LH and fasting insulin concentrations (trivariate association), with age and BMI z-score held fixed at 12.4 years and 2.4, respectively.
