Levator hiatus dimensions and pelvic floor function in women with and without major defects of the pubovisceral muscle.
Trial report in International urogynecology journal, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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 present study was to compare pelvic floor morphology and function in women with and without major defects of the pubovisceral muscle.
methodsOne hundred fifty-seven women with pelvic organ prolapse participated in this cross-sectional study. Participants answered a symptom questionnaire and underwent clinical and three- and four-dimensional transperineal ultrasound examination. Pelvic floor muscle maximum voluntary contraction (MVC), endurance, and resting vaginal pressure were registered with a vaginal balloon catheter. Offline analyses were performed for the presence of major pubovisceral muscle defects (PVMD) and hiatal dimensions.
resultsThe levator hiatus dimensions at rest and contraction were significantly larger in women with than without major PVMD. Mean differences in levator hiatus area between women with and without major PVMD were: rest 1.9 cm(2) 95% confidence intervals (CI) 0.21-3.7, P = 0.028 and contraction 2.75 cm(2) 95% CI 1.0-4.5, P =0.002; and Valsalva maneuver mean difference was 0.82 cm(2) 95% CI 2.18-3.83, P = 0.543. Women with major PVMD had lower MVC and endurance measurements as compared with women without major PVMD, but the differences were not statistically significant.
conclusionsWomen with major pubovisceral muscle defects have larger hiatal dimensions at rest and at contraction than women without PVMD. We were unable to prove the corresponding relationship for hiatal dimensions on Valsalva.
