1 · What the graph read from it

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.

2 · The registry

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: To determine differences in endometrial cavity anteroposterior diameter, thickness, volume, and diameter lines of uterine body and thickness, and volume of upper, middle, and lower regions of the endometrium in infertile women using a new method for three-dimensional (3D) reconstruction based on two-dimensional (2D) ultrasound images. Methods: This retrospective cross-sectional study included a total of 81 infertile women, who underwent 2D ultrasound standard examination. We created 3D models of the uterine body, endometrial cavity, and endometrium based on 2D ultrasound images. The parameters that were measured and analyzed in a 3D plane included volume and diameter lines of endometrial cavity, surface area, thickness, volume, and diameter lines of uterine body, and surface area, thickness, and volume of upper, middle, and lower region of the endometrium. These parameters were used for comparisons between normal and arcuate uterus, between non-pregnant and pregnant infertile women, and between nulliparous and multiparous infertile women. The differences between the different regions of the endometrium and the correlations between age and the parameters were also determined in this study. Results: Endometrial cavity length, and middle and lower regions of the endometrial volume in the normal uterus were 39.63±7.61 mm, 1,307.92±1,034.40 mm Conclusions: This study provides references for the volume and thickness of the endometrium in the different anatomical regions of normal and arcuate uterus. Age mainly affects the upper region of the endometrium. The 3D measurement provides a precise way to quantify the morphological parameters of gynecological diseases.
