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
backgroundEarly venous drainage is a critical diagnostic feature of arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs). However, other conditions associated with early venous drainage can mimic AVMs and AVFs and mislead the treating physician team. OBSERVATIONS: The authors present a unique case of a 56-year-old man with new left hemianopsia. Workup with magnetic resonance imaging and magnetic resonance angiography had revealed cortical enhancement and early venous drainage, possibly caused by an AVF or AVM. Catheter angiography confirmed the presence of early venous drainage of specifically the right occipital lobe. The early venous drainage occurred as the result of local hyperperfusion limited to the right occipital lobe. Subsequent electroencephalography confirmed focal seizure activity in the right occipital lobe. After seizure control with multiple antiepileptic medications, the patient regained his vision. Repeat digital subtraction angiography revealed restoration of normal cerebral blood flow. LESSONS: Early venous drainage observed during catheter angiography can be associated with seizure activity. Differentiation from other conditions, such as AVM, AVF, or ischemic stroke, is critical to facilitate prompt and appropriate treatment.
