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

Epilepsy results from an imbalance between excitation and inhibition of neurons, with 30-40% of cases being temporal lobe epilepsy (TLE). This study aimed to prioritize autophagy-related genes and explore their potential links to immune features in human hippocampal tissue of TLE. Two hippocampal transcriptomic datasets (GSE202101 and GSE11882) were analyzed to identify autophagy-related differentially expressed genes (ARDEGs). Functional enrichment, regulatory network, and immune cell infiltration analyses were performed. LASSO regression and consensus clustering were applied. Exploratory assessment of the candidate gene signature was conducted in an independent dataset (GSE256068). Immunohistochemistry (IHC) on clinical specimens assessed protein expression of candidate signature genes. An eight‑gene candidate signature was derived, and subsequent PPI network analysis revealed LARP1, EIF4G1, and TSC2 as hub genes among them. Exploratory assessment in an independent dataset partially replicated the expression patterns of PYCARD, EIF4G1, and TSC2, whereas LARP1 showed an opposite expression trend; overall model performance remained modest. Increased activated mast cells were observed in TLE samples, while higher levels of plasma cells, CD8⁺ T cells, and regulatory T cells were observed in controls. Two exploratory clusters with distinct immune correlation patterns were identified. IHC showed upregulation of ABL1, TSC2, and SPP1 protein levels in TLE tissue. This study prioritizes a set of autophagy-related candidate genes in human hippocampal tissue and provides an exploratory framework linking them to local immune features in TLE. Further validation in larger independent cohorts is warranted before any clinical interpretation.
