Upper Panel: Linear regression analysis of log transforms of circulating concentrations of testosterone (T, closed circles), androstenedione (Adione, closed squares) and androstenediol (Adiol, open triangles) versus the log transform of dehydroepiandrosterone sulfate (DHEAS). Compared to T, both Adione and Adiol are more strongly related to DHEAS.
Lower panel: The log transform of all circulating Adiol concentrations are highly associated with the estimate of circulating androgenicity (open circles) while there is no relationship between the log transform of Adiol and circulating estrogenicity when all Adiol measurements are included.
