Gut microbial-derived indole-3-propionate improves cognitive function in Alzheimer's disease.

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
Intermittent fasting (IF) offers a potential strategy to counteract Alzheimer's disease (AD) progression. In our 16-week study on AD transgenic mice, IF positively affected cognitive function and reduced amyloid-β (Aβ) accumulation, verifying the IF's role in modulating neuroinflammation. Multiomics integration revealed strong links between IF-induced hippocampal gene expression, gut microbiota, and serum metabolites beneficial for cognition. Indole-3-propionic acid (IPA) emerged as a pivotal microbial metabolite. Blocking its neuronal receptor, pregnane X receptor (PXR), abolished IF's effects. Human data paralleled these findings, showing lower IPA levels in patients with mild cognitive impairment and AD than in controls. IPA supplementation and IPA-producing
