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
Endovascular management of spinal dural arteriovenous fistula (DAVF) is arduous because of complex angioarchitecture and motion artifacts and is limited by the two-dimensional (2D) view. However, cone beam computed tomography (CBCT) acquisitions with selective injections allow 3D multiplanar reconstructions contributing to high diagnostic, anatomical and safety value. In this study, we described the use of virtual injection software (VIS) computed from CBCT acquisition and already used for prostatic and cerebral embolization, for the endovascular management of spinal DAVFs (EmboAssist, GE HealthCare, Chicago, USA). The VIS has been designed to facilitate the analysis of the patient's vasculature during the planning of embolization procedures to define the afferent pedicles to the shunt and the incidence of oblique projection, allowing for a better anatomical understanding and helping for the selection of 2D incidence. Combined with 3D roadmapping, VIS allows vessel tracking for selective catheterism and embolization. The VIS is a useful tool for planification and navigation during endovascular treatment of spinal DAVF with a safety value.
