Three-dimensional endoanal ultrasound measurements for the assessment of perineal body size in a cohort of Swedish nulligravidae.

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
introductionDespite the perineal body's important functional role, few studies have specifically evaluated its size in women. Existing three-dimensional ultrasound studies typically involve small samples, often including both nulliparous and parous women, and focus on measuring internal and external sphincter thickness rather than the perineal body itself. MATERIAL AND
methodsThis cross-sectional study primarily aimed to measure the size of the perineal body in a population of nulligravidae (n = 148) using three-dimensional endoanal ultrasonography. Secondary aims were to (1) evaluate the feasibility and reproducibility of 3D ultrasound interpretation across raters with varying levels of experience and (2) investigate how perineal body measurements correlated with body composition.
resultsThe study participants had a mean age of 31 years (SD ± 6), a mean height of 167 cm (SD ± 5.9), and a mean body mass index (BMI) of 25.3 kg/m
conclusionsStandardized 3D endoanal ultrasonography provides reproducible measurements of the perineal body in nulligravid women and measurements correlated moderately with body composition. This suggests the use of this imaging method in asymptomatic populations and future research on pelvic floor function.
