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
Hemifacial spasm (HFS) is a disorder that causes involuntary movements of the ipsilateral facial muscles because of vascular compression of the facial nerve. Microvascular decompression (MVD), a surgical procedure to detach the culprit vessel from the nerve is believed to be the most effective treatment for HFS. Nevertheless, in the rare case in which the vessel penetrates the nerve, positioning the vessel sufficiently far from the nerve is challenging. In this report, a case of right HFS in a 54-year-old man with an anterior inferior cerebellar artery that had penetrated the nerve fiber cleft between the facial nerve and the nervus intermedius is presented. In the present case, the patient achieved relief from spasm, and postoperative facial hemiplegia was prevented by splitting the cleft slightly, gently moving the vessel, and affixing it to the petrous part of the temporal bone. The anatomic relationship between the facial nerve and the offending vessel must be properly understood, which must be carefully manipulated in such "penetration-type" HFS cases.
