Proportion of women with miscarriages with different MoM cutoffs and time to diagnosis of miscarriage. (A–C) Mean of the proportion of women with miscarriages with different cutoffs of multiples of gestation-specific median for kisspeptin (A), βhCG (B), and the sum of kisspeptin and βhCG) (C). (D–F) Mean (95% CI) of the multiples of gestation-specific median for kisspeptin (D), βhCG (E), and the sum of kisspeptin and βhCG (F) by the time to confirmation of miscarriage (in weeks). The miscarriage groups were compared by the Kruskal-Wallis test. ∗∗P<.01, ∗∗∗P<.001. βhCG = beta human chorionic gonadotropin; CI = confidence interval; MoM = multiple of median.
