AFC ^a	15.5 ± 6.7	16.0 ± 7.0	0.681
FSH (mIU/mL) ^a	7.6 ± 3.0	8.2 ± 5.2	0.383
LH (mIU/mL) ^a	5.1 ± 3.2	5.1 ± 2.3	0.984
E₂ (pg/mL) ^a	45.5 ± 45.8	35.2 ± 20.8	0.156
Gravidity ^b	1.0 (0.0–5.0)	2.0 (1.0–7.0)	< 0.001
Parity ^b	0.0 (0.0–1.0)	0.0 (0.0–1.0)	0.273
No. of curettage ^b	0.0 (0.0–3.0)	2.0 (0.0–6.0)	< 0.001

^aValues are mean ± standard deviation.
^bValues are median and Min-Max.
P value: For continuous variables, it can be obtained by Kruskal Wallis rank sum test. If the count variable has a theoretical number < 10, it can be obtained by Fisher’s exact probability test.
