Response to CC at different doses. R50 = responders to 50 mg; NR50 = nonresponders to 50 mg; R100 = responders to 100 mg; NR100 = nonresponders to 100 mg; R150 = responders to 150 mg; NR150 = nonresponders to 150 mg.

3. Figure 2
Plasma concentrations of En (top) and Zu (middle) and their ratio (bottom) during the three cycles of treatment with CC. Values are expressed as mean ± SE; the vertical broken line on day 21 (D21) indicates the end of the cycle when patients were assessed for ovulation. A = responders and nonresponders to 50 mg; B = responders and nonresponders to 100 mg; C = responders and nonresponders to 150 mg.
