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: Retinoblastoma (RB) is one of the most common primary intraocular malignancies in children. Its pathogenesis involves multiple signaling pathways that remain incompletely understood, and effective treatment strategies are still limited. This study aims to identify ferroptosis-related biomarkers and explore their roles in immune infiltration and therapeutic response in RB using bioinformatics approaches. Methods: To investigate the role of ferroptosis in RB, we analyzed the microarray dataset GSE166173 to identify differentially expressed genes (DEGs) between healthy controls and RB patients. Ferroptosis-related DEGs were further screened, and least absolute shrinkage and selection operator (LASSO) regression was applied to identify candidate genes at the intersection of RB and ferroptosis. Key genes were subsequently examined by gene set enrichment analysis (GSEA), gene set variation analysis (GSVA), immune infiltration analysis, and drug sensitivity prediction. Results: Three ferroptosis-associated genes- Conclusions: This study identified three ferroptosis-related genes (FRGs) as potential diagnostic biomarkers of RB. Their association with immune cell infiltration provides new insights into the molecular mechanisms of RB and highlights potential therapeutic opportunities.
