Pelvic floor muscle variables and levator hiatus dimensions: a 3/4D transperineal ultrasound cross-sectional study on 300 nulliparous pregnant women.
Article in International urogynecology journal, 2014. 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 aims of the present study were to investigate the correlation among vaginal resting pressure and pelvic floor muscle (PFM) strength and endurance, and the correlation between the same variables and levator hiatus (LH) dimensions in nulliparous pregnant women.
methodsThis was a cross-sectional study of 300 nulliparous pregnant women, mean age 28.7 years (SD 4.3) and pre-pregnancy BMI 23.9 kg/m(2) (SD 3.9), assessed at mean gestational week 20.8 (±1.4). Vaginal resting pressure and PFM strength and endurance were measured using a high precision pressure transducer connected to a vaginal balloon. LH dimensions (transverse and anterior-posterior diameters_ and LH area were assessed using 3/4D transperineal ultrasound in the axial plane of minimal hiatal dimensions using render mode. The Pearson correlation was used to analyze correlations among vaginal resting pressure and PFM strength and endurance, and between PFM variables and LH dimensions. Level of significance was set at 0.05.
resultsPelvic floor muscle strength and vaginal resting pressure were significantly, but weakly correlated (r = 0.198, p < 0.001). PFM strength and endurance showed a strong correlation (r = 0.929, p < 0.001). High vaginal resting pressure was moderately correlated with a small LH area at rest (r = -0.451, p < 0.001), but there was no significant correlation neither between PFM strength and LH area at rest (r = -0.012, p = 0.84) nor between muscle endurance and LH area at rest (r = -0.014, p = 0.81). A strong PFM contraction correlated moderately with reduction of the LH area (r = -0.367, p < 0.001).
conclusionsPelvic floor muscle strength and endurance are strongly correlated, butdo not correlate with a smaller LH area at rest.
