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

rationalePsychiatric disorders are a largely elusive aspect of obesity, representing a growing public health concern. In this regard, a large body of evidence indicates a pivotal role of disturbed autophagic flux in the pathogenesis of obesity-associated neuropsychiatric deficits.

objectivesThis work was designed to evaluate the effects of the glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide, which is increasingly utilized for the management of chronic obesity, on the depressive/cognitive deficits in the high-fat diet (HFD) rat model of obesity with an emphasis on its hippocampal mechanistic backgrounds.

methodsThe effects of chronic liraglutide administration (subcutaneous; 300 µg/kg/day for 28 days) were investigated on depressive-like phenotypes, cognitive deficits, and hippocampal phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamycin (mTOR)-regulated autophagy.

resultsChronic liraglutide treatment amended the HFD-induced depressive-like phenotype (in the sucrose preference and the forced swimming tests) and cognitive deficits (in the Morris water maze test). Moreover, liraglutide enhanced the hippocampal expression of brain-derived neurotrophic factor (BDNF), PI3K, Akt, p-Akt, and p-mTOR and downregulated the expression of the autophagic markers (Beclin-1, LC3) and the inflammatory markers (TNF-α, IL-6) with amelioration of HFD-induced hippocampal neurodegeneration.

conclusionsThis work highlights the antidepressant and pro-cognitive properties of liraglutide in HFD-exposed rats, which could be mediated through amelioration of the disrupted PI3K/Akt/mTOR signaling activity with a possible impedance of the exaggerated autophagy-mediated neurodegenerative cascades. Indeed, this study highlights that liraglutide is not only effective in weight control, but its effects also extend to managing obesity-related psychiatric disorders.
