TP53, HIF1A, and CDKN2A in Hepatocellular Carcinoma: Roles in Senescence, Ferroptosis, and Prognosis.
Article in Clinical and translational gastroenterology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
introductionThe aim of this study was to evaluate the association between genes related to cellular senescence and ferroptosis and their relevance to hepatocellular carcinoma (HCC).
methodsGenes associated with senescence and ferroptosis in HCC were retrieved from public databases. A protein-protein interaction network was constructed to identify for hub genes and validate their expression. Diagnostic performance was evaluated using receiver operating characteristic curve analysis, while prognostic significance was determined through Kaplan-Meier analysis. A prognostic nomogram model was developed based on selected hub genes and tumor node metastasis staging.
resultsA total of 52 senescence-ferroptosis-related genes were identified in HCC. Receiver operating characteristic analysis indicated moderate to high diagnostic efficacy for TP53 (area under the curve [AUC] = 0.723, CI: 0.669-0.776), JUN (AUC = 0.733, CI: 0.659-0.806), RELA (AUC = 0.854, CI: 0.808-0.901), and CDKN2A (AUC = 0.953, CI: 0.932-0.974). Kaplan-Meier analysis revealed that TP53 , HIF1A , and CDKN2A were significantly associated with overall survival in patients with HCC. A nomogram model incorporating these 3 genes and tumor node metastasis staging achieved a concordance index (C-index) of 0.699. Calibration curves indicated concordance between the predicted and observed survival probabilities at 1-, 2-, and 3-year intervals. DISCUSSION: The senescence-ferroptosis-related genes TP53, HIF1A, and CDKN2A demonstrated potential as diagnostic and prognostic biomarkers in HCC. The developed nomogram may support individualized prognostic assessment and inform early diagnostic and therapeutic strategies in patients with HCC.
