Interaction between body mass index (BMI) and menopausal stage for (A) estradiol (P<0.001), (B) FSH (P=0.008), and (C) inhibin b (P=0.004) from the full multivariable models.
Hormone values are the geometric mean with 95% confidence interval, estimated from multivariable models that adjusted for race, age and smoking and within women correlation due to repeated measurements. The reduced significance level with the Bonferroni correction for within-group comparisons at each menopausal stage is P=0.003.
N=436 with 3,581 observations for estradiol, 3,578 observations for FSH and 3,051 observations for inhibin b.
