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: The optimal treatment strategy for acute ischemic stroke following atherosclerotic cervical internal carotid artery (ICA) occlusion remains unclear. Angioplasty alone may increase the risk of re-occlusion and recurrent ischemic stroke. This study investigated imaging changes after performing angioplasty alone. Methods: We retrospectively reviewed consecutive patients who underwent mechanical thrombectomy (MT) from 2017 to 2024. Patients who underwent angioplasty with atherosclerotic cervical ICA occlusion were initially screened. We performed MT, along with angioplasty for the cervical artery, during the acute procedure. Additional treatment (stenting or endarterectomy) was scheduled after a week or more. Magnetic resonance imaging was performed to assess the stenotic lesion. Results: Of the 262 patients who underwent MT, 11 had atherosclerotic cervical ICA occlusion. Seven of them who underwent angioplasty alone were included in this study. Follow-up magnetic resonance angiography (MRA) showed a significant improvement in stenosis diameter compared with after the acute procedure (2.5 ± 0.5 mm vs. 2.0 ± 0.6 mm, Conclusion: In appropriately selected patients treated with angioplasty alone, follow-up MRA showed a trend toward gradual improvement of the stenotic lesion without re-occlusion or neurological deterioration. MRA may be useful for non-invasive and repeated monitoring of stenotic changes over time.
