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
Recent evidence suggests that microglial activation, driven by a metabolic shift towards glycolysis, was involved in the pathogenesis of Alzheimer's disease (AD). Although sphingolipid (SL) dysregulation has been linked to AD, the role of 1-deoxysphinganine (deoxySO), an atypical and neurotoxic SL, on microglial glycolytic reprogramming remains unclear. We measured serum deoxySO levels in AD patients and evaluated their association with cognitive performance. In APP/PS1 mice, we examined cerebral deoxySO level and the effects of deoxySO supplementation on cognitive function, neuropathology, and microglial activation. In vitro, BV2 microglia were used to assess inflammatory and metabolic changes via qPCR, western blot, ELISA, and RNA-seq analyses. The serum deoxySO levels were significantly elevated in AD patients, which was positively correlated with cognitive impairment. APP/PS1 mice exhibited increased cerebral deoxySO level, and supplementation with deoxySO could exacerbate cognitive deficits and Aβ plaque accumulation. Moreover, deoxySO supplementation increased microglial activation and enhanced inflammation in vivo and in vitro AD models. qPCR analysis identified disease-associated microglia (DAM) as a key deoxySO-responsive subpopulation, while RNA-seq revealed significant enrichment of genes related to glycolytic metabolism and inflammatory responses. Subsequently, qPCR confirmed that deoxySO promoted glycolytic metabolic reprogramming, which promoted DAM activation, thereby aggravating AD pathology. These findings identify deoxySO as a critical metabolic driver that links to microglial glycolytic activation and neuroinflammation, suggesting that targeting deoxySO-mediated metabolic pathways may offer a novel therapeutic strategy for AD.
