1 · What the graph read from it

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.

2 · The registry

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

Chordomas are rare, locally invasive, and slow-growing neoplasms that originate from remnants of the primitive notochord. They account for approximately 1% of all intracranial tumors and are typically found in the sacrococcygeal region or at the skull base. Purely intradural intracranial chordomas are exceptionally rare, with only 67 cases documented to date, to the best of our knowledge. These tumors are generally situated near the midline. We present the case of a 67-year-old male who developed hemiparesis and hemihypoesthesia 6 years after undergoing surgery for a classical spinal chordoma that was purely extradural. Magnetic resonance imaging revealed a mass in the frontoparietal area, initially suggestive of an intraaxial tumor. However, intraoperative findings indicated that the lesion was extraaxial, and histopathological evaluation confirmed it as an intradural chordoma. To our knowledge, this is the first reported case of a chordoma within the brain parenchyma and away from the midline.
