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

The glucagon-like peptide-1 receptor (GLP-1R) has emerged as a promising therapeutic option for alcohol use disorder (AUD), yet the underlying mechanisms and neurocircuitry involved remain unclear. This study aimed to analyze GLP-1R gene expression changes in brain regions associated with alcohol's effects, including the prefrontal cortex (PFC), nucleus accumbens (NAc), and hippocampus (HIP), in mice following 42 days of voluntary ethanol consumption (VEC; 10% v/v) and postmortem samples from 18 patients with AUD. Additionally, we examined the expression of OPRM1 (mu-opioid receptor) and BDNF (brain-derived neurotrophic factor), key targets related to alcohol intake and reward, in the NAc and HIP, respectively. GLP-1R gene expression was significantly reduced in all brain regions of ethanol-exposed mice and AUD patients. These reductions paralleled decreased OPRM1 and BDNF expression in the NAc and HIP, respectively. Pearson and Spearman correlation analyses revealed no significant associations between gene expression and age, RIN, pH, postmortem interval (PMI), body mass index (BMI), smoking status, age of onset of alcohol use, or years of drinking. In summary, chronic alcohol consumption in humans or mice was associated with decreased GLP-1R gene expression in brain regions involved in the reinforcing effects of ethanol. These findings open new avenues for further research into how this emerging receptor could serve as a potential biomarker and therapeutic target in AUD.
