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
objectiveAcute vertebrobasilar occlusion can led to a fatal outcome, but lack of established procedures poses many difficulties in its management. Although mechanical thrombectomy (MT) has shown positive outcomes recently, high reocclusion rate remains a hurdle. This study is to share experience and to review technical challenges of rescue angioplasty and/or stenting (RAS) for refractory occlusions after MT in posterior circulation ischemic stroke (PCIS).
methodsOut of 494 patients with acute ischemic stroke from January 2014 to December 2022 in a Hospital, PCIS was identified in 50 patients. 2 extracranial vertebral artery occlusion patients were excluded. For 48 patients, MT was applied as the primary treatment. RAS was done for reocclusion after MT in 15 patients. We evaluated patient characteristics and clinical course, emphasizing the technical aspects of treatment.
resultsCompared to those without rescue procedures, RAS group had a higher percentage of large artery atherosclerosis as an etiology (p<0.001), long segment occlusions (p=0.03), and was more likely to involve posterior inferior cerebellar artery (p=0.007). There was no difference in functional outcome at 6 months between these two groups. Reopening could not achieve (N=2, 13.3%) and procedural complication rate (iatrogenic rupture) is 6.7% in RAS group. Rescue procedures were complicated with dissection, plaque rupture and migration, device damage, and misplacement of the balloon/stent. Avoiding these traps, finding true lumen, and reconstructing the flow by connecting the proximal and distal normal were the keys to the successful RAS.
conclusionsRAS could be inevitable during endovascular treatment for PCIS and being aware of possible events and technical strategies would navigate interventionists to successful recanalization and the better outcomes.
