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
BACKGROUND AND
objectivesBased on laparoscopic views, we hypothesized that the involvement of the lateral compartment of the pelvis (LCP) by deep infiltrating endometriosis can be inferred by observing retraction of the obliterated umbilical artery (OUA) toward the abdominal cavity. We sought to verify the association between the retraction of the OUA and the presence of endometriosis in the ipsilateral LCP (parametrium, paracervix, or paracolpium).
methodsThis preplanned, retrospective, cross-sectional study evaluated 76 women with deep endometriosis at a private referral center. Using magnetic resonance imaging, the retraction of OUA was represented by its distance from the rectus abdominis (four different measurements were used). The diameter of the OUA was also measured and considered. T2-weighted imaging of the pelvis were obtained in two planes (sagittal and axial) and from two reference points: the proximal angle of the artery (measurement 1) and a point immediately above (measurement 2). The measurements were assessed through an exploratory multivariate principal component analysis. The associations were tested using the bivariate, non-parametric statistical Mann-Whitney U test.
resultsThe presence of endometriosis of all LCP examined was 34.2% (95% confidence interval: 26.8-41.7) with the highest percentage in the paracervix. The retraction of the OUA was greater in women with endometriosis in the ipsilateral LCP for all four measurements and was statistically significant for three of them: Sagittal 1 (p = .011), Sagittal 2 (p = .015), Axial 1 (p = .021), and Axial 2 (p = .093). The OUA diameter was not associated with its retraction (p = .392).
conclusionRetraction of the OUA toward the abdominal cavity is associated with the presence of endometriosis in the ipsilateral paracervix.
