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
Cerebral glucose hypometabolism has been consistently associated with Alzheimer's disease (AD). With extensive efforts to eliminate AD pathologies, including the removal of amyloid-β (Aβ) plaques and hyperphosphorylated Tau, strategies aimed at restoring glucose metabolism in the brain regions most affected by AD are believed to have significant clinical implications. In this study, we demonstrated that glucose hypometabolism preceded neuronal death in triple-transgenic AD (3xTg-AD) mice, likely attributable to reduced expression of glucose transporter type 1 (GLUT1) or glucose transporter type 3 (GLUT3). Furthermore, we observed aberrant activation of the integrated stress response (ISR) pathway in AD models, with Aβ and Tau phosphorylation contributing to the activation of the ISR and subsequent reduction in GLUT1/3 expression. Inhibiting ISR activation by utilizing the ISR inhibitor ISRIB can effectively restore GLUT1/3 expression in both in vitro and in vivo models. Importantly, ISRIB treatment improved cognitive function and brain glucose metabolism in 3xTg-AD mice. Our findings suggest that targeting the ISR pathway to restore GLUTs expression may be a potential therapeutic strategy for AD.
