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

objectiveAnorexia nervosa (AN) is a severe eating disorder associated with brain volume reduction, glial cell loss, microbiome alterations, and dysregulated pro-inflammatory mechanisms. However, the underlying cellular mechanisms remain inadequately elucidated, and interventions addressing these alterations are lacking.

methodThis study employed a chronic activity-based anorexia (ABA) rat model to investigate hippocampal glial and neuronal cell alterations, inflammation, and microbial modifications in the gut. Omega-3 fatty acids and a multi-strain probiotic were examined as potentially protective agents. Cell count, proliferation, and apoptosis rates of microglia, neurons, astrocytes, and oligodendrocytes were analyzed in the hippocampus. Furthermore, local gene expression of pro-inflammatory cytokines and microRNA was measured. The hippocampal volume was determined longitudinally using 7-Tesla MRI scans before and after starvation. Finally, the fecal microbiome was analyzed to identify potential associations with brain and clinical characteristics.

resultsResults confirmed the previously described reduction in astrocytes and newly demonstrated a decrease in oligodendrocytes in the hippocampus. Increased levels of IBA1-positive cells and pro-inflammatory cytokines suggest microglial activation in this region. Administering omega-3 and probiotics to starved animals reduced neuroinflammation and microglial activation in the hippocampus, resulting in significantly increased neuronal cell counts in the omega-3 group. Microbiome composition was primarily affected by the ABA model, and to a lesser extent by omega-3 and probiotics. DISCUSSION: These findings support the involvement of microglial activation in the pathogenesis of AN, potentially relevant to hippocampal re-learning and thus important for psychotherapy. Further, omega-3 and probiotics may serve as adjunct therapeutic strategies by modifying inflammation.
