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
We report a case of distal anterior cerebral artery (DACA) aneurysm presenting with subdural hematoma (SDH) without subarachnoid hemorrhage (SAH). A patient in his fifties presented with headache. Fluid-attenuated inversion recovery magnetic resonance imaging revealed SDH in the interhemispheric fissure and left frontotemporal region. SAH was not detected. Computed tomographic angiography revealed aneurysms in the left internal carotid artery (ICA) and DACA. The patient underwent frontotemporal craniotomy, which confirmed an unruptured ICA aneurysm, followed by bilateral frontal craniotomy for clipping of DACA aneurysm. The left DACA aneurysm was identified as the source of the SDH. Intraoperative findings showed adhesion between the aneurysm body and falx cerebri, explaining the SDH formation. Literature review identified only six reported cases of SDH without SAH due to DACA aneurysm. Evidence suggests that DACA aneurysms have a relatively higher propensity to cause SDH without SAH, likely due to the anatomical characteristics of the parent vessel and aneurysm projection.
