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
Fully endoscopic microvascular decompression is increasingly being used to treat hemifacial spasm; however, its efficacy must be validated by comparing it with conventional microscopic microvascular decompression. In this study, we aimed to compare the surgical outcomes of microsurgical and endoscopic microvascular decompression for hemifacial spasm and discuss the usefulness and risks of endoscopic treatment. A total of 40 patients with hemifacial spasm were retrospectively evaluated at a single institution between 2016 and 2022, including 33 patients who underwent microscopic microvascular decompression (microvascular decompression group) and 7 patients who underwent fully endoscopic microvascular decompression group, which was chosen for patients with sufficient space in the cerebellopontine cistern for endoscopic manipulation. Statistical analyses of the microvascular decompression group and the endoscopic microvascular decompression group were performed to compare patient background and surgical outcomes. No significant differences in age, sex, or affected side were observed between the 2 groups. At the 6-month follow-up, substantial improvement was observed in more than 85% of the patients in each group. Delayed facial palsy and mild lower cranial nerve palsy, such as hoarseness, were more common in the endoscopic microvascular decompression group than in the microvascular decompression group, although there were no significant differences in the rate of complications between the 2 groups. All complications were alleviated within 3 months after surgery. During endoscopic microvascular decompression, interference between the endoscope and instruments can cause neural damage owing to the limited space along the petrosal surface of the cerebellum. Our results suggest that endoscopic procedures cannot always be used as a substitute for conventional microscopic microvascular decompression.
