Figure 3. Scatter plot of FSH concentrations by cohort.
For the peri- (Peri) and postmenopausal (Post) cohorts, results are sorted into hCG-positive and hCG-negative populations on basis of the 5.0 IU/L cutoff for a positive hCG test. The bars indicate the median FSH concentration. The dashed line is the limit of functional sensitivity. Pre, premenopausal; y, years.
