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
Objective: Spontaneous closure of dural arteriovenous fistulas (AVFs) has been reported. However, complete spontaneous obliteration of a jugular tubercle venous complex (JTVC)-centered intraosseous AVF appears to be rare. We report a case of a JTVC-centered intraosseous AVF that spontaneously occluded after diagnostic cerebral angiography. Case Presentation: A 34-year-old man presented with a 6-month history of pulsatile tinnitus. MRA suggested an arteriovenous shunt in the JTVC. DSA revealed an intraosseous AVF with a shunt pouch located within the JTVC, supplied by multiple feeders. The lesion drained exclusively into the posterior condylar vein without direct communication with the internal jugular vein, indicating a single and restricted venous drainage pathway. Immediately after angiography, the patient developed headache and nausea, and the tinnitus resolved. Follow-up MRA at 1 month demonstrated disappearance of the shunt, and repeat angiography confirmed complete obliteration. No recurrence was observed at 6 months. Conclusion: This case suggests that a JTVC-centered intraosseous AVF with a single and restricted venous drainage pathway may be prone to spontaneous occlusion. Nevertheless, the natural history of such lesions remains unclear, and changes in symptoms should prompt careful imaging evaluation because they may reflect alterations in venous drainage patterns rather than complete shunt obliteration. Long-term imaging follow-up is essential.
