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
Transcatheter aortic valve implantation (TAVI) carries a small but serious risk of periprocedural stroke. Prompt recognition and rapid management are essential to prevent permanent neurological injury. We describe an acute ischemic stroke occurring during TAVI for bicuspid aortic stenosis, immediately identified by the interventional cardiologist through carotid angiography. The patient developed sudden left hemibody weakness and aphasia after balloon predilatation, and angiography revealed an occlusion of the right middle cerebral artery (M1). While maintaining hemodynamic stability with valve implantation, the operator restored partial flow in the ophthalmic artery and activated the stroke team. Mechanical thrombectomy was rapidly performed using an aspiration catheter, achieving complete recanalization, with a modified Thrombolysis in Cerebral Infarction grade 3 within 30 min of symptom onset. Post-procedural imaging confirmed the absence of hemorrhage, and neurological deficits improved markedly. This case highlights how immediate in-laboratory carotid angiography performed by the structural interventional cardiologist can significantly shorten the diagnostic-to-reperfusion interval and facilitate ultra-rapid multidisciplinary rescue in periprocedural stroke. Learning objective: Immediate in-laboratory carotid angiography by the structural operator may significantly shorten time-to-reperfusion in periprocedural stroke. Peripheral interventional skills are essential for structural cardiologists, enabling them to promptly recognize and address extracardiac complications. Multidisciplinary collaboration between interventional cardiologists, neurologists, and interventional radiologists is vital to achieve optimal outcomes in life-threatening complications. The absence of cerebral embolic protection did not compromise the outcome, consistent with recent randomized evidence showing no significant reduction in clinical stroke with routine use of protection devices.
