Intraspinal pilocytic astrocytomas: An overview and 2-D illustrative resection technique video.
Article in Surgical neurology international, 2022. 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
backgroundSpinal cord pilocytic astrocytomas (PAs) are rare and typically occur in pediatric patients. While PAs are often well-circumscribed and amenable to gross total resection, they sometimes harbor infiltrative components that can invade normal cord parenchyma.
methodsHere, we present a 59-year-old female with a progressive right-sided hemi-sensory loss, right-sided hemiparesis, and gait imbalance. The preoperative T2 magnetic resonance imaging revealed a large loculated cystic tumor that focally compressed the dorsal medulla, while the contrast study revealed a 1.3 cm homogenously enhancing expansile intramedullary mass centered at the C1 level.
resultsThe patient underwent a C1-2 laminectomy followed by gross total intramedullary tumor resection utilizing intraoperative dorsal column mapping. There were no operative complications. The patient had preserved motor strength and an expected dorsal column dysfunction, which largely resolved over 9 months postoperatively.
conclusionHere, we provide a broad overview of PAs, in addition to a case study/technical note that includes a 2-D intraoperative video detailing the resection technique.
