Usefulness of somatosensory-evoked potentials for monitoring cerebral perfusion during transcarotid transcatheter aortic valve replacement: a case report.

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
backgroundTranscarotid transcatheter aortic valve replacement (TAVR) is a safe procedure with a low incidence of cerebral infarction and has recently become the first-choice alternative approach. This procedure requires temporary occlusion of the common carotid artery (CCA). CCA clamping during surgery may help reduce the risk of embolism caused by debris; however, the risk of hemodynamic stroke cannot be entirely ruled out. Therefore, intraoperative monitoring of cerebral ischemia is essential. Regional oxygen saturation (rSO CASE PRESENTATION: A 92-year-old male patient with a history of dyspnea on exertion was diagnosed with severe aortic valve stenosis (AS) using transthoracic echocardiography (TTE). Contrast-enhanced computed tomography (CT) revealed a shaggy aorta extending from the aortic arch to the descending aorta. Preoperative magnetic resonance angiography (MRA) of the head showed slight narrowing of the anterior communicating artery. Considering the patient's age, frailty, and vascular pathology, we performed transcarotid TAVR while monitoring rSO
