The changes in 10‐h LH pulse mass attributable to progesterone appeared less pronounced in women with PCOS compared to controls after adjusting for these covariates (ratio of ratios, 0.46 [95% CI, 0.22–0.99]; uncorrected p = 0.047), but this was not significant after Bonferroni‐correction (p = 0.094). The gene discussed is PLOD1; the disease is polycystic ovary syndrome.
