Translabial three-dimensional ultrasound investigation of the levator hiatus in postpartum women.

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
purposeThis study utilized translabial three-dimensional ultrasound to investigate the morphological characteristics of the levator hiatus and provide sonographic evidence for assessing pelvic floor dysfunction in postpartum women.
methodsTwo-hundred and one singleton primiparae without any complications underwent translabial three-dimensional ultrasound at 6 and 18 weeks after delivery, with 12 participants lost to follow-up at 18 weeks. Fifty nulliparae were enrolled as the control group. Levator hiatal morphology at rest and on Valsalva maneuver was assessed by experienced sonographers, specifically evaluating the anteroposterior diameter, left-to-right diameter, and area.
resultsIn postpartum women at 6 weeks after delivery, all the levator hiatal parameters were significantly higher compared with those of the control group. At 18 weeks, the hiatal parameters were better than at 6 weeks but still higher than in the nulliparous controls. In all three groups, the hiatal parameters were significantly higher during the Valsalva maneuver than at rest.
conclusionsPostpartum women are prone to develop pelvic floor dysfunction as shown by an enlarged levator hiatus. Translabial three-dimensional ultrasound can be used to effectively assess the morphology and structural alterations of the levator hiatus in postpartum women, providing reliable pelvic floor imaging for early screening, diagnosis, and prevention of pelvic floor dysfunction.
