Figure 5
Weekly creatinine-corrected PDG and P4 in the exploratory cohort. (A) anovulatory cycles (n = 22, 14 women), (B) ovulatory cycles (n = 20, 13 women). Values are mean ± SEM. Ovulation was determined by reaching a threshold cutoff in PDG and week 3 designated by the rise in PDG/P4. C:Receiver operator characteristics (ROC) for peak P4:Cr from each 4-sample consecutive series. Area under the curve 0.952 (95% CI 0.89 to 1.01). Blue bars, PDG:Cr: urinary creatinine-corrected pregnanediol glucuronide, red bars, P4:Cr: urinary creatinine-corrected progesterone. Dashed line: ROC, solid line: identity.
