2. Figure 1
FSH, inhibin B, activin A, and FS 288 by study group. Data are mean ± standard error of the mean. For inhibin B, mean concentrations in the PM and OVX+ET groups were near the limits of assay detection, thus the standard error bars for these groups are not shown. Mean E2 concentrations are indicated at the top of the FSH panel. Significant group differences (∗, ∗∗) were determined by Kruskal-Wallis analysis of variance and post hoc Mann-Whitney U-test.
