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 describe an instructive case of post-thrombectomy subarachnoid hemorrhage (PTSAH) by sylvian hematoma removal. Case Presentations: An 83-year-old female presented with an acute cardiogenic right M1 occlusion. After the thrombectomy with combined stent retriever and aspiration technique with total five passes, TICI 2b reperfusion was achieved; however, CT imaging displayed subarachnoid hematoma (SAH) along the right sylvian fissure. Throughout the approach, contrast extravasation was not confirmed. The SAH grew up to become the sylvian hematoma; therefore, removal of the sylvian hematoma was conducted. An abrupt arteriole tear around the distal M2 of parietal artery was confirmed as bleeding point and those teared arteriole's stumps were electrically coagulated not to re-bleed. Conclusion: We suggest that the PTSAH is possible even in invisible-extravasation cases and the sylvian hematoma removal is effective to elucidate the etiology of the PTSAH, and is a reliable method to prevent the re-bleeding and is anticipated to improve the prognosis. Craniotomy is required for medically resistant PTSAH after thrombectomy, and avulsion of the pial artery can be the cause.
