Massive arachnoid granulation in the transverse sinuses on CT myelogram.

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
Giant arachnoid granulations have been previously reported in the literature, with the largest documented measuring 6 cm and usually associated with significant clinical symptoms. Herein, we present a patient with a massive, irregular-shaped arachnoid granulation occupying both transverse sinuses, a finding that has not yet been reported. The patient, who had a history of transvenous CSF-venous fistula (CVF) embolization, presented with persistent left occipital headaches. Digital subtraction myelography (DSM) to investigate a residual or recurrent CVF yielded negative results. Contrast enhanced brain MRI showed a nonenhancing lobulated lesion in the expected location of, but distinct from the transverse sinuses. The patient was later started on indomethacin, which completely resolved his headaches, consistent with the diagnosis of hemicrania continua. This indicated that the arachnoid granulation was an incidental finding despite its unusual size.
