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
Background: Intracranial vertebral artery stenosis is a significant cause of ischemic stroke. Intravascular optical coherence tomography (OCT), known for its high resolution, can accurately analyze the microstructure components of the stenotic vessel wall. Although widely used in the cardiovascular system, its application in intracranial atherosclerotic diseases of intracranial arteries remains limited. This study aimed to utilize OCT as a novel imaging modality for vessel wall microstructure analysis in patients with intracranial atherosclerosis. Specifically, it analyzed the vascular walls of 15 patients with severe intracranial vertebrobasilar artery stenosis before and after endovascular stent treatment. Methods: A retrospective analysis was conducted from 7 March 2023 to 26 March 2024 at The First Affiliated Hospital of Harbin Medical University, focusing on the neurosurgical endovascular stent treatment and OCT evaluation of 15 cases of intracranial vertebrobasilar artery stenosis (70-90%). All lesions were located in the V4 segment of the vertebral artery. Results: OCT accurately identified the vessel wall microstructures in patients with intracranial vertebrobasilar artery stenosis before and after endovascular stent treatment. Identified structures included fibrous plaques, lipid plaques, calcified plaques, ruptured plaques, intraluminal thrombosis, vascular dissection, microchannels, macrophages, cholesterol crystals, healing plaques, tissue prolapse, stent thrombosis, and stent adherence. Following endovascular stent treatment and OCT only one patient experienced symptomatic complications. Conclusions: The evaluation of intracranial vertebrobasilar arteries using OCT was shown to be safe and feasible. This technique aids in the diagnosis and treatment of cerebrovascular diseases. However, this preliminary study should be validated through prospective large-scale studies.
