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
purposeThe analysis of the microstructure of dural arteriovenous fistulas (DAVFs) plays a crucial role in achieving the successful embolization of DAVFs associated with complex microanatomy. Recent advancements in high-resolution cone-beam computed tomography (CBCT) enable detailed visualizations of the microstructure of the shunt point. In this study, we retrospectively evaluated the efficacy of this imaging modality in terms of the clinical and angiographic outcomes of the endovascular approach.
methodsWe retrospectively analyzed a total of 83 cases of dural arteriovenous fistulas (AVFs), including spinal lesions. High-resolution CBCT images with an 8-inch field of view and 1024 × 1024 pixel matrix detector at 80 kV were acquired. The anatomical variation and configuration of DAVFs were analyzed and compared with superselective angiography findings.
resultsThe sensitivity of the shunt location was over 96.3%, and the tip of the microcatheter in the affected sinus was well visualized during the procedure. In particular, this imaging modality was effective in identifying the exact shunt point in relation to the initial foot of the vein in cases of spinal and spinal epidural DAVFs. The quality of the images depended on the regional concentration of the contrast and the timing of acquisition. The arrival time of the contrast to the objects was an important factor in visualizing the microanatomical structure.
conclusionAppropriately adjusted CBCT acquisition parameters are sufficient to visualize the microanatomy of lesions and adjacent structures and sufficient to identify the shunt point, even in cases of complex DAVFs.
