Arterial spin labelling could detect the occlusion of inferior petrosal sinus for cavernous sinus dural arteriovenous fistula.

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
Several reports indicate that arterial spin labelling (ASL) MRI is useful for the diagnosis, identification of cortical venous reflux, and assessment of therapeutic effect in dural arteriovenous fistula (dAVF). However, there is no reports indicating the utility of ASL in the identification of venous sinus obstruction. We herein report the case of a 72-year-old woman who presented with diplopia and right trigeminal neuralgia due to bilateral cavernous sinus dAVF. Digital subtraction angiography (DSA) showed temporal occlusion of the inferior petrosal sinus (IPS) and ASL indicated hyperintense signal in the IPS. The ASL signal could indicate venous stasis soon after the occlusion based on the serial changes of IPS patency and occlusion observed in the DSA.
