AMH and polycystic ovary syndrome: Figure 4e showed an increasing OR with higher follicle counts, with an OR of about 2.25 (95% CI: 1.40–2.55) for 15 follicles. After adjusting age, weight, cycle length, AMH levels, and follicle no. (L), the likelihood of PCOS was positively correlated with the follicle no. (R) (non-linear, p < 0.0001, Figure 4f).
