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
purposePalatal surgery for snoring or obstructive sleep apnea is commonly performed; however, the vascular anatomy of the soft palate is not well described. The purpose of this study was to evaluate the vascular anatomy of the soft palate.
methodsThis study was performed on 22 adult cadaveric heads. All specimens were prepared with vascular injections using red liquid silicone through the common carotid artery. The palate was then harvested and decolorized, and the vascular anatomy was studied.
resultsOf 22 specimens, 20 had sufficient uptake of the silicone dye. The anterior and posterior branches of the ascending palatine artery were the main feeding vessels of the soft palate; however, they were not always present simultaneously. The anterior branch alone was identified 25% of the time (5/20), while the posterior branch alone was found in 35% (7/20) of specimens. Both anterior and posterior branches were simultaneously present in 40% (8/20) of cases. Mean diameter of the anterior branch (0.73 ± 0.09 mm) was significantly greater than that of the posterior branch (0.48 ± 0.08 mm, p < 0.001). Mean vertical distance from the palatal arch to the posterior branch was 9.3 ± 2.4 mm.
conclusionsThe soft palate is supplied by the anterior and posterior branches of the ascending palatine artery; however, the arteries were not always present simultaneously. In cases where the anterior branch is absent and the posterior branches terminate close to the uvula, injury to the primary blood supply to the palate might occur more frequently during surgery.
