Thrombolytic therapy in vertebrobasilar dolichoectasia patients with acute posterior circulation cerebral infarction: a case series analysis.
Article in Thrombosis journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Vertebrobasilar dolichoectasia (VBD) is a rare cerebrovascular condition marked by elongation and dilation of the vertebral and basilar arteries. Patients with VBD often have strokes in the posterior circulation, but the safety and efficacy of intravenous thrombolysis (IVT) in this population are not well established. We report two cases of acute posterior circulation infarction in VBD patients who received IVT with tenecteplase. Patient 1 was a 56-year-old man. He received IV tenecteplase (0.25 mg/kg) one hour after arrival, and his deficits resolved (NIHSS 0) by the end of infusion with no hemorrhagic complications. He remained stroke-free at 1 year on dual antiplatelet therapy and statin.Patient 2 was a 39-year-old man. He received IV tenecteplase 78 min after arrival and similarly recovered to NIHSS 0 with no bleeding. He was asymptomatic at 3 months but had a recurrent cerebellar stroke at 6 months due to poorly controlled hypertension and hyperlipidemia. These cases suggest that IVT can be effective in VBD-related stroke, but emphasize the importance of aggressive risk factor management.
