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: We report a rare case of delayed intracerebral hemorrhage that was possibly related to venous outflow impairment after transarterial embolization (TAE) with Onyx (Medtronic, Dublin, Ireland) for a tentorial dural arteriovenous fistula (DAVF). We also discuss the potential role of susceptibility-weighted imaging (SWI) in the early detection of postoperative venous circulatory disturbance. Case Presentation: A 65-year-old man with a history of atherosclerotic stroke was diagnosed with a left tentorial DAVF (Borden type III, Cognard type IV). TAE with Onyx was performed, and complete obliteration of the shunt was achieved. MRI obtained 1 day after embolization revealed FLAIR hyperintensity near the shunt point and hypointense signals on SWI, suggesting venous outflow impairment. On postoperative day 6, the patient developed a large subcortical hemorrhage that required emergency decompressive craniotomy. Follow-up angiography confirmed persistent shunt occlusion. The patient was subsequently transferred to a rehabilitation facility with a modified Rankin Scale score of 4. Conclusion: This case illustrates a rare instance of delayed hemorrhage after Onyx TAE for a tentorial DAVF, possibly related to venous outflow impairment after embolization. SWI may be a useful adjunctive imaging modality for the early detection of postoperative venous circulatory disturbance.
