Table 1. Comparison of basic data from eligible selected POP patients and non-POP controls.

	Age (year)	BMI (kg/m2)	Parity (times)	Menopause status	Family history of POP
Non-POP group (n = 48)	53.31 ± 10.65	21.49 ± 2.31	2.34 ± 0.87	35/48	3/48
POP group (n = 46)	55.46 ± 8.59	24.47 ± 2.73	2.63 ± 0.97	37/46	5/46
POP II (n = 24)	54.23 ± 12.51	24.12 ± 1.78	2.79 ± 1.54	17/24	3/24
POP III (n = 22)	57.85 ± 11.39	25.38 ± 2.52	2.95 ± 1.34	20/22	2/22

Note: Continuous variable was examined by independent samples t-test and its results were shown by mean ± standard deviation. Based on the POP-Q score results, all patients were identified as POP-Q score > stage II. BMI, body mass index; POP, pelvic organ prolapse; POP-Q, pelvic organ prolapse quantification.
