1 · What the graph read from it

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.

2 · The registry

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

Alzheimer's disease (AD) is a major devastating neurodegenerative disorder afflicting majorly the geriatric population. Emerging studies augur the connection of gut dysbiosis and circadian disruption with the early onset of AD. Gut dysbiosis is characterized by dysregulated gut microbiota signature and compromised intestinal integrity, which provokes the translocation of bacterial metabolites into the systemic circulation. Noteworthy, gut-derived metabolites like calprotectin, trimethylamine-N-oxide, kynurenine, isoamylamine, and short-chain fatty acids play a key role in AD pathogenesis. Circadian dysregulation also corresponds with the exacerbated AD pathogenesis by accumulating Aβ and tau proteins. Moreover, circadian dysregulation is one of the causative factors for gut dysbiosis. This review discusses the complex interplay between the microbiota-gut-brain axis, circadian rhythmicity, and the emergence of AD. We reviewed preclinical and clinical studies on AD describing potential biomarkers of gut dysbiosis and circadian dysregulation. The identification of new biomarkers associated with the microbiota-gut-brain axis and circadian rhythmicity may help in early diagnosis and development of targeted therapies for mitigating neurodegenerative AD.
