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
aimTo investigate the role and mechanism of uridine (URI), an active component in deer antler, in improving cognitive impairment in Alzheimer's disease (AD) mice.
methodThe APP/PS1 mouse model was used for AD. After URI gavage administration, cognitive behavioral changes in mice were detected using the Morris water maze, eight-arm maze, and novel object recognition tests. Levels of inflammatory cytokines and lactate, pyruvate in the cortex were measured. The proportions of IBA-1 and CD86 cells in tissues were detected, and the expression of key glycolysis proteins was examined. Network pharmacology was employed to analyze the targets of URI-AD-glycolysis. AAV-CMV-shHSP90 was injected to knock down brain HSP90 levels to further explore the anti-AD mechanism of URI. In vitro, primary microglia were used to detect the proportion of CD86+ M1 cells and glycolysis levels.
resultURI can improve cognitive impairment in AD mice, with significant changes in cognitive ability and behavior. URI reduces glycolysis levels, the proportion of M1 cells (CD86+), and the activation degree of microglia, while inhibiting the activation of HSP90-HIF-1α. Network pharmacology analysis revealed that HSP90 is a major target of URI. When HSP90 is inhibited, the effect of URI is diminished. In vitro experiments showed that URI can inhibit the M1 polarization of microglia and reduce glycolysis levels.
conclusionURI can inhibit microglial glycolysis and M1 polarization via HSP90/HIF-1α, thereby improving cognitive behavioral deficits in AD mice due to neuroinflammation. Uridine in deer antler is a novel small molecule for anti-AD.
