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

AIMS/

introductionDiabetic retinopathy (DR) is a prevalent chronic complication of type 2 diabetes mellitus (T2DM), contributing significantly to vision impairment. Circular RNAs (circRNAs) have emerged as key regulators in the pathogenesis of DR. This study aimed to investigate the differential expression profiles and potential functions of circRNAs in patients with DR compared to those without DR. MATERIALS AND

methodsIn this single-center, prospective study, serum samples from 20 T2DM patients with DR and 20 without DR were analyzed using the Arraystar Human circRNA Expression Profile V2.0 microarray. An additional cohort of 40 patients (20 DR and 20 without DR) was used to validate selected circRNAs via quantitative reverse transcription PCR (qRT-PCR). Enriched signaling pathways were identified using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. CircRNA-miRNA-mRNA interaction networks were constructed using bioinformatics tools.

resultsA total of 376 circRNAs were differentially expressed, including 169 upregulated and 207 downregulated circRNAs. qRT-PCR validation confirmed five downregulated circRNAs and three upregulated circRNAs, which were selected for competing endogenous RNA analysis. The circRNA-miRNA-mRNA network analysis revealed that hsa_circRNA_407262 (also known as circRNA LOC389906) may act as a miRNA sponge regulating key signaling pathways, including wingless/integrated, gonadotropin-releasing hormone, tumor necrosis factor, and rat sarcoma pathways.

conclusionsThis study identified five downregulated and three upregulated circRNAs associated with DR. Among them, hsa_circRNA_407262 may play a crucial role in the pathological process of DR and holds potential as a candidate biomarker for early diagnosis.
