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 case in which coil embolization was performed for an angiographically occult ruptured anterior communicating artery aneurysm (Acom AN). Case Presentation: A 91-year-old man was admitted to our hospital because of sudden deterioration of consciousness. Computed tomography (CT) revealed a diffuse subarachnoid hemorrhage in the basal cisterns, and CT angiography identified a 5-mm Acom AN. The next day, a catheter angiogram slightly visualized the neck portion of the Acom AN, despite no apparent visualization of the aneurysmal sac. We suspected intraluminal thrombosis of ruptured Acom AN, and intraaneurysmal coil embolization was performed to prevent re-rupture. By referring to the size and projection of the aneurysmal sac on CT angiography, a microcatheter was guided into the neck portion, and 3 platinum coils were successfully placed within the aneurysm without any complications. Eight days after coil embolization, recanalization of the aneurysm was suspected on magnetic resonance imaging (MRI). Another MRI obtained 17 days after coil embolization revealed gradual recanalization of the aneurysm, which was confirmed on catheter angiogram obtained 22 days after coil embolization. Additional intraaneurysmal coil embolization resulted in complete occlusion. Subsequently, the patient had an uneventful course without rebleeding and was transferred to a rehabilitation center. Conclusion: We performed intraaneurysmal coil embolization for an angiographically occult ruptured Acom AN by referencing the neck position, aneurysm projection, and aneurysm size on CT angiography. Thus, angiographically occult aneurysms can be treated with endovascular coil embolization despite the need for close follow-up studies to detect recanalization.
