Continuous data was presented as mean ± standard deviation, and categorical variable was presented as percentile (number)

Significant subgroup differences (Bonferroni pairwise comparison, p < 0.05/3) are indicated by superscripts “a: low AMH vs. average AMH in women < 35 yrs”, “b: low AMH vs. high AMH in women < 35 yrs”, “c: average AMH vs. high AMH in women < 35 yrs”, “d: low AMH vs. average AMH in women ≥35 yrs”, “e significant difference for low AMH vs. high AMH in women ≥35 yrs”,“f significant difference for average AMH vs. high AMH in women ≥35 yrs”
