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: Current guidelines have not recommended an upper age limit for endovascular thrombectomy (EVT) in patients with large vessel occlusion (LVO) stroke. However, elder age links to an increased risk of poor outcome. This study aimed to investigate the efficacy of EVT in elderly versus non-elderly patients and determine the respective factors of poor outcome. Methods: Three hundred and two consecutive patients with LVO-stroke who underwent EVT were included, and we used sensitivity analysis with restricted cubic spline to define 75 years as the inflexion point. Participants were thus dichotomized into elderly (≥75 years) and non-elderly (<75 years) groups. Brain frailty on neuroimaging was evaluated using the global cortical atrophy (GCA) scale and the Fazekas scale for white matter lesions (WML). The primary outcome was 3-month functional outcome, and the secondary outcomes were EVT efficacy and safety. Results: Elderly patients had significantly higher incidences of hypertension, diabetes mellitus, atrial fibrillation, and more severe GCA and WML. The rate of good outcome in elderly patients was 32%, significantly lower than non-elderly patients (54%, Conclusion: GCA and WML play pivotal roles for the functional outcomes in elderly patients undergoing EVT for LVO-stroke, providing valuable and practical information for early prediction of long-term prognosis.
