In the effectiveness analysis, there were 11 missing cases, accounting for about 7% of the study population. Therefore, in the effectiveness analysis, the data of the missing persons were processed with missing values. The mean ± standard deviation was used for the normal distribution data, the independent sample t-test was used for the comparison, the P50 (P25, P75) was used for the non-normal distribution data, and the rank combination test was used for the inter-group comparison. POPDI-6, Pelvic Organ Prolapse Distress Inventory 6; CRAD-8, Colorectal-Anal Distress Inventory 8; UDI-6, Urinary Distress Inventory 6.
