  1. Correlations are based on all participants but excluding the data from the acAN_T2 assessments (n = 279 total; for Leptin n = 260; for LH, FSH, Estradiol n = 248). Bold font indicates significant correlations after adjusting the p-value for the number of multiple comparisons which were 28 using the Bonferroni methods (i.e. p < 1.8 × 10−3). The exact p-values are reported in Supplemental Table 6.
