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
backgroundGlossopharyngeal neuralgia (GPN) is a rare disorder characterized by severe, episodic pain along the sensory distribution of cranial nerve (CN) IX. Bilateral GPN presents unique challenges for consideration of microsurgical treatment due to potential risks of postoperative dysphagia and cardiac arrhythmias associated with resection of bilateral CN IX/X. Here, the authors describe successful staged bilateral microsurgical rhizotomy of CN IX and upper CN X rootlets to treat bilateral GPN. OBSERVATIONS: A 54-year-old female presented with right GPN and underwent a right retrosigmoid craniotomy with rhizotomy, resulting in complete resolution of pain. During the following year, the patient developed left GPN and was considered for the same surgical intervention. However, prior to pursuing surgical intervention, evaluation of her swallowing function was conducted to stratify her risk of pharyngeal sensory denervation or dysphagia, and to confirm her suitability for left-sided rhizotomy. Given the patient's normal oropharyngeal swallowing function on videofluoroscopic swallow study, she underwent left retrosigmoid craniotomy with rhizotomy. At the 3-month follow-up, the patient described complete resolution of pain and normal swallowing function. LESSONS: With the use of comprehensive patient evaluation between surgical stages, staged bilateral microsurgical rhizotomy is a feasible and safe treatment option for carefully selected patients with bilateral GPN. https://thejns.org/doi/10.3171/CASE25359.
