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

backgroundAlcohol use disorder (AUD) is associated with chronic heavy or repeated binge alcohol abuse, which can cause alcohol-related brain damage (ARBD) marked by neurobehavioral, cognitive, and motor deficits. The anterior frontal lobe and cerebellar vermis are two of the major targets of ARBD in humans with AUD and in experimental alcohol exposed models. Alcohol's neurotoxic and neurodegenerative effects include impairments in signaling through insulin and insulin-like growth factor (IGF) pathways that regulate energy metabolism. This human AUD study was inspired by a recent report suggesting that dysfunction of the frontal lobe incretin network in experimental ARBD is linked to known impairments in brain insulin/IGF signaling.

objectiveThe overarching goal was to investigate whether AUD is associated with dysfunction of the brain's incretin network, focusing on the cerebellum and frontal lobe.

methodsFresh frozen postmortem cerebellar vermis and anterior frontal lobe tissues from adult male AUD (

resultsAUD was associated with significantly increased NfL immunoreactivity in both the cerebellar vermis and anterior frontal lobe. However, the patterns of AUD-related alterations in gut hormone immunoreactivity differed regionally. AUD reduced pancreatic polypeptide immunoreactivity in the cerebellar vermis, and GIP, GLP-1, leptin, and ghrelin in the frontal lobe.

conclusions(1) Increased NfL may serve as a useful biomarker of neurodegeneration in AUD. (2) AUD's adverse effects on neuroendocrine signaling networks differ in the cerebellar vermis and anterior frontal region, although both are significant targets of ARBD. (3) The finding of AUD-associated reductions in frontal lobe GIP and GLP-1 suggests that therapeutic targeting with incretin receptor agonists may help restore energy metabolism and neurobehavioral and cognitive functions linked to their networks.
