Figure 2. Assessment of Equivalence at 12 Months between a Retropubic and a Transobturator Midurethral Sling as Treatment for Urinary Incontinence.

Figure 2

The difference in the rates of treatment success (retropubic minus transobturator) at 12 months is shown, with two-sided 95% confidence intervals (CIs). A value greater than 0 percentage points indicates that there is a higher success rate with the retropubic sling than with the transobturator sling; a value less than 0 indicates that there is a higher success rate with the transobturator sling than with the retropubic sling. If the entire confidence interval lies within a prespecified range of −12 to +12 percentage points, the retropubic and transobturator slings can be considered to be equivalent.
