Artificial Intelligence for the Automated Measurement of Hiatal Dimensions.
Observational study in International urogynecology journal, 2026. 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 levator hiatus is an important determinant of pelvic organ prolapse and prolapse recurrence after surgery. Manufacturers are now offering automatic determination of hiatal dimensions.
methodsThis was an observational study using data sets of 437 women attending a urogynaecological unit in 2024 and 2025. All had 4D pelvic floor ultrasound using a Voluson E 22 system with SonoPelvic™ software. Data sets obtained on Valsalva were used for automated measurements. Manual measurements were performed later on stored data sets blinded against all other data. For statistical analysis we employed ICC and Bland Altman plots. Patients in whom measurements differed by ≥20% were reviewed.
resultsThe 437 women seen during the study period presented with stress urinary incontinence (n = 304), urgency urinary incontinence (n = 334) and symptoms of pelvic organ prolapse (n = 229). Automated measurements yielded a mean of 25.45 (4.08-64.76) cm
conclusionAutomated analysis by the current version of SonoPelvic™ shows a strong correlation with manual measurements, except in women with highly abnormal pelvic organ support. The software is under continuous development for which several recommendations are made.
