Figure 2: Relationships between levels of testosterone, SHBG, free androgen index (100·testosterone/SHBG), and BMI as evaluated using ANCOVA with BMI group as a main factor and age of the subject as a covariate (for details see statistical data analysis). The circles with error bars represent the group means with their 95% confidence intervals as computed for least significant difference (LSD) multiple comparisons (p=0.05). The confidence values, which do not overlap, represent statistical significant difference between the corresponding groups. Statistical significance: NS=not significant, **p<0.01, ***p<0.001.
