Sonographic assessment of compression effect on urethra following transobturator MUS.
Article in International urogynecology journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introduction and hypothesisThe aim of this study was to investigate the relationship between compression effect exerted by the sling on the urethra using translabial ultrasound and the prognosis of sling surgery in women for stress urinary incontinence (SUI).
methodsWe retrospectively reviewed 151 women with SUI who had undergone either a TVT-Abbrevo (n = 81) or TVT-O (n = 70) procedure. Preoperative and 12-month postoperative assessments including sonographic data, urinary symptoms and signs were compared. Objective and subjective success rates were assessed at 12 months postoperatively.
resultsOverall, 140 patients (92.7%) were objectively cured and 138 patients (91.4%) were subjectively cured of SUI 12 months after the operation with no significant differences between groups (p > 0.05). After both the TVT-Abbrevo and TVT-O procedures, the shortest distance between the tape and the urethral cavity line (TU) on straining (objective cure 4.1 mm vs. 4.5 mm, subjective cure 4.1 mm vs. 4.4 mm), the changes of the angle (∆) between the two arms of the sling (objective cure 15.8° vs. 20.8°, subjective cure 16.5° vs. 21.3°) and the gap between the sling and symphysis pubis (objective cure 9.9 mm vs. 12.1 mm, subjective cure 9.8 mm vs. 12.4 mm) were significantly smaller in the success group (p < 0.05). Analysis of ultrasound measurements in women reporting success and those reporting failure of the procedure showed the ∆TU (objective cure 1.6 mm vs. 0.9 mm, subjective cure 1.6 mm vs. 1.0 mm) and the angle on straining (objective cure 93.4° vs. 89.2°, subjective cure 94.3° vs. 88.9°) to be significantly bigger (p < 0.05). However, none of the assessed sonographic variables showed any significant differences between the TVT-Abbrevo and TVT-O groups.
conclusionsThe change in distance between the tape and urethral cavity line in the center of the urethra in the mid-sagittal plane after straining is an effective indicator of the compression effect exerted by the sling on the urethra after a mid-urethral sling (MUS) procedure and may contribute to both objective and subjective cure rates postoperatively.
