Failure was defined as any of the following: retreatment for prolapse, any POP-Q measure beyond the hymen, or presence of bother on PFDI vaginal bulge question. Under the permanent failure state assumption, the number of participants shown at each visit includes all participants who were still participating in the study or had a failure outcome prior their withdrawal. Similarly, the denominator number of participants for the cumulative failure at each visit includes all participants who were still participating in the study and attended the visit or had any failure outcome prior their withdrawal or missed visit.

The Pelvic Floor Distress Inventory is a 20-question, validated, self-reported instrument used to evaluate pelvic floor symptoms. It consists of an overall scale (range: 0-300) comprised of 3 sub-scales: 1. Pelvic Organ Prolapse Distress Inventory (range: 0-100), 2. Colorectal Anal Distress Inventory (range: 0-100), and 3. Urinary Distress Inventory (range: 0-100). The range of responses for all questions is 1-4 with (1) Not at all, (2) Somewhat, (3) Moderately, and (4), Quite a bit. Subscale scores are calculated by multiplying the mean value of all questions answered by 25 for the subscale. The range of score for each subscale is: 0-100 with 0 (least distress) to 100 (most distress). The PFDI is calculated as the sum of the three subscales. Lower scores indicate better function / fewer symptoms for the PFDI scale, POPDI subscale, CRADI subscale, and UDI subscale. Change from baseline = (Month [12, 24, 36] Score - Baseline Score).

Functional Activity Scale measuring the impact of incontinence symptoms on a woman's daily activities is composed of 13 questions about normal and physically strenuous daily activities. The range of responses on the individual questions is (1) No difficulty,... (5) Not able to do it. Scores are calculated by subtracting from the maximum sum (5*13=65) the product of the mean response and number of questions, then dividing by the total range of sums (65 - 13 = 52) and multiplying by 100. The range of responses is: 0-100 with 0 (worse functionality) to 100 (Better functionality). Change = (Month [6, 12, 18, 24, and 36] Score - Baseline Score).
