Incidental Subependymoma of the Floor of the Fourth Ventricle: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Subependymomas are rare, slow-growing intraventricular tumors that are typically discovered incidentally and seldom present with transient sensory symptoms in young adults. We report the case of a 22-year-old woman who presented with episodic migratory paresthesias and was found on brain MRI to have a small fourth-ventricular lesion radiographically consistent with subependymoma. The patient's sensory symptoms resolved spontaneously, and no further episodes occurred. Conservative management with serial imaging was pursued. At the six-month follow-up, the lesion remained stable, and the patient was asymptomatic. Subependymomas most commonly become symptomatic due to cerebrospinal fluid obstruction, whereas episodic migratory paresthesias are unusual. This case highlights the value of early MRI in young adults with atypical sensory symptoms, which may reveal incidental yet clinically significant findings and help avoid unnecessary invasive testing. Small, non-obstructive fourth-ventricle subependymomas can be safely managed with observation, demonstrating excellent short-term clinical and radiographic outcomes.
