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

Solitary fibrous tumors (SFTs), encompassing lesions previously classified as hemangiopericytoma, are rare mesenchymal neoplasms. Intracranial SFTs confined to the dural venous sinus are extremely rare and may mimic cerebral venous sinus thrombosis (CVST). A 76-year-old man presented with impaired consciousness and an elevated D-dimer level. Non-contrast computed tomography and magnetic resonance imaging (MRI) revealed an intraluminal lesion within the posterior superior sagittal sinus. The lesion exhibited mild T2-weighted hyperintensity, without internal flow voids or associated mass effect. CVST was suspected, and anticoagulation therapy was initiated. Imaging follow-up was discontinued after symptomatic improvement. One year later, the patient re-presented with a headache. MRI demonstrated marked enlargement of the lesion, with extension beyond the dura into the adjacent brain parenchyma. Biopsy and subsequent surgical resection confirmed a World Health Organization Central Nervous System grade 1 SFT. Small intrasinus SFTs may closely mimic CVST; therefore, careful imaging follow-up is essential for accurate differentiation.
