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

Background: Limbal epithelial cells (LECs) play a crucial role in preserving ocular surface stability and ensuring the normal function of the corneal epithelium. The functional capacity of LECs diminishes with age, playing a part in the onset of ocular diseases linked to aging. Although long non-coding RNAs (lncRNAs) are key regulators of gene expression and are known to be involved in numerous ocular pathologies, their expression dynamics during aging in LECs are not yet well characterized. Methods: High-throughput RNA sequencing and computational analysis were utilized to characterize age-related differences in mRNA and lncRNA in human LECs derived from young and old donors. 90 lncRNAs and 177 mRNAs with significant age-associated expression changes were identified. Functional enrichment was assessed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. A competing endogenous RNA (ceRNA) network was constructed using Cytoscape and cytoHubba, focusing on the interaction between lncRNAs, miRNAs and mRNAs. Results: The study identified the potential ceRNA network, SDHAP2_miR-17-5p/miR-20b-5p_RAB11FIP1, that might be crucial in age-related changes of the LECs. Quantitative RT-PCR validated the expression for SDHAP2 (downregulated), miR-17-5p (upregulated), miR-20b-5p (upregulated), and RAB11FIP1 (downregulated) in the old group, consistent with transcriptome data. Functional analysis suggested this network may be involved in oxidative stress responses and cellular senescence. Conclusion: Our findings reveal age-associated lncRNA and mRNA expression alterations in human LECs and highlight the SDHAP2_miR-17-5p/miR-20b-5p_RAB11FIP1 ceRNA network as a potential molecular indicator and therapeutic entry point for age-related ocular surface diseases.
