3. FIGURE 2
Receiver operating characteristic curve for endometrial dating for all biopsies (black line), biopsies obtained in the midluteal (days 21–22) phase (green line), and biopsies obtained in the late luteal (days 26–27) phase (red line). The y-axis of the graph represents the proportion of women in each group correctly classified as infertile by a biopsy out-of-phase by more than 1 day (♢), by more than 2 days (□), by more than 3 days (▵), and by more than 4 days (X), whereas the x-axis represents the proportion of women in each group incorrectly classified as infertile in each group. The dotted diagonal line represents a test that does not discriminate between true and false positives.
