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 albumin-to-globulin ratio (AGR) is a biomarker reflecting both nutritional status and inflammation, which has recently been implicated in the development of ischemic stroke. However, its potential association with the occurrence of cerebrovascular stenosis remains unclear. This study aimed to investigate the relationship between AGR and the incidence of cerebral atherosclerotic stenosis. Methods: Data from 766 adult patients with acute ischemic stroke (AIS) were included in this cross-sectional analysis. Binary logistic regression was used to evaluate the independent association between AGR and the risk of various cerebrovascular stenosis, including anterior circulation stenosis, posterior circulation stenosis, intracranial and extracranial stenosis. To explore the potential non-linear relationship between AGR and these outcomes, restricted cubic spline models were employed to further clarify these associations. Stratified analyses by body mass index (BMI), age, and sex were additionally conducted to explore the correlation between AGR and cerebral atherosclerotic stenosis under different conditions. Results: Patients with cerebral atherosclerotic stenosis had lower AGR levels than those without corresponding vascular stenosis. After adjusting for multiple covariates, AGR levels were negatively associated with the presence of stenosis in the posterior circulations (OR = 0.59, 95%CI = 0.38 ~ 0.90, Conclusion: Higher AGR is associated with a reduced risk of multiple cerebral atherosclerotic stenosis. AGR levels are significantly associated with the presence of specific stenosis subtypes and could be hypothesized as a marker for risk stratification; this utility requires validation in prospective cohorts.
