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
backgroundSurgical fenestration of dorsal brainstem cysts is commonly challenging to perform because of difficulties in selecting an optimal surgical corridor. Herein, the authors report a case of a dorsal brainstem cyst that was successfully treated with a navigation-guided endoscopic transcerebellar approach. OBSERVATIONS: A 9-year-old boy was diagnosed with optic pathway pilocytic astrocytoma at the age of 3 years. Subsequently, he required multiple procedures for tumor recurrence and growth of the cystic component. Despite these treatments, the dorsal brainstem cyst gradually enlarged, causing compression of the brainstem and fourth ventricle. A navigation-guided endoscopic transcerebellar approach for cyst fenestration was planned. The cyst wall was widely fenestrated via the suprafacial triangle on the floor of the fourth ventricle. Postoperatively, the patient developed transient truncal ataxia. However, he was discharged home after 2 weeks without neurological deficits. LESSONS: A navigation-guided endoscopic transcerebellar approach can be effective for dorsal brainstem cyst treatment. The surgical corridor is direct and linear, thereby allowing easy and reliable access. The entry point into the cyst should be located in the rostral portion of the floor of the fourth ventricle. Hence, it is important to create a sufficiently wide communication between the cyst and the fourth ventricle. https://thejns.org/doi/10.3171/CASE26161.
