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
backgroundVestibular schwannomas are common posterior fossa tumors, often managed with stereotactic radiosurgery (SRS) due to its low invasiveness and high tumor control rates. However, malignant transformation of vestibular schwannoma (MTVS) is a rare but serious complication with a poor prognosis. OBSERVATIONS: The authors present a case of MTVS occurring 29 years after initial SRS, the longest latency reported. A 68-year-old woman developed sudden facial nerve paralysis, with magnetic resonance imaging revealing tumor regrowth. Surgical removal and histopathological analysis confirmed malignant transformation, characterized by spindle-shaped atypical cells and significant p53 positivity. Despite multiple surgeries and radiation therapy, the tumor exhibited rapid regrowth and cerebrospinal dissemination, leading to a poor prognosis. LESSONS: This case underscores the critical importance of long-term monitoring after SRS, as malignant transformation can occur decades later. Additionally, it highlights the potential necessity for early intervention during malignant transformation to improve patient outcomes, despite the challenges in identifying effective treatments for MTVS. https://thejns.org/doi/10.3171/CASE24526.
