Figure 2: A box-and-whisker plot expressing the distribution of absolute PBAC scores at 12months in relation to re-intervention.
Logistic regression with adjustment for study gave unreliable results. The trial by Busfield et al. had a relatively small sample size and did not use satisfaction as an outcome measurement. Therefore, this study was excluded from the analyses for satisfaction. The trials by Brun et al. and Cooper et al. were the only two studies in which nearly none of the women received surgical re-intervention 12 months after treatment. These studies were therefore excluded from the analyses of surgical re- intervention.

PBAC score at 12 months
PBAC12m is strongly associated to satisfaction (OR 0.16 [95%CI 0.11-0.24]) and surgical re-intervention (OR 2.3 [95%CI 1.8-2.8]). Repeating the analysis for multiples of the P75 gave OR 0.8 [95% CI 0.74-0.86] for satisfaction and OR 1.6 [95% CI 1.4-1.8] for reintervention).
