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: Three-dimensional ultrasound (3D-ultrasound) and elastography are imaging techniques facilitating the diagnosis of gynaecological diseases and uterine anomalies. These non-invasive ultrasound applications may be of important added diagnostic value in gynaecological ultrasonography. Objectives: The main objective of this study was to develop a simple and cheap in vitro model for elastography and 3D-ultrasound, with an adaptable probe-target distance. The target should be visible within the model and its hardness should be modifiable. The orientation and inclination of the model should also be adjustable. Materials and Methods: We used a boiled chicken egg in a gel basis as this mimics the elastic properties of human tissues. Different boiling times were compared with the stiffness at elastography. Both 3D-ultrasonography and strain elastography were conducted with a Voluson™ E10 4-9 MHz vaginal probe. Results: Altering the eggs' boiling times modulates the levels of stiffness, and hence the aspect on elastography. Conclusions: Our model can help trainees to practice acquisition and interpretation of elastography images. This cheap and easy-to-reproduce, in vitro "chicken-egg-model" allows for education and training of 3D-ultrasound and elastography, without causing discomfort to patients. What is new?: We created a cheap and easy to reproduce in vitro model for the education of 3D-ultrasound and elastography.
