Non-viral HCC miRNA profiling reveals miR-1972 as a potential positive prognostic marker.
Article in Non-coding RNA research, 2025. 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
Background & Aims: Hepatocellular carcinoma (HCC) is the third deadliest cancer worldwide. Its high mortality is primarily attributed to late-stage diagnosis. While mutations in driver genes, such as those encoding β-catenin (CTNNB1), tumor protein p53 (TP53), and telomerase reverse transcriptase promoter (TERTp) are well-documented in the literature, dysregulation of microRNAs (miRNAs), small non-coding RNAs that serve as crucial translational regulators, remains poorly understood. Methods: We conducted microRNA profiling by microarrays in 45 paired (tumor and non-tumor adjacent tissue) samples from non-viral HCC patients. We performed clinical correlation, ROC analysis and survival analysis of time to recurrence (TTR), disease-free survival (DFS) and overall survival. Results: We identified 23 significantly dysregulated miRNAs (p ≤ 0.05, fold change ≥2). We investigated their differential expression and its relationship with clinical and pathological variables. Further, we found that miRNA-1972 may serve as an important positive prognostic marker because its high levels were associated with longer TTR and DFS. Significant positive results were obtained in receiver operating characteristic analysis for miR-1972, miR-3651 and miR-486-5p. Conclusion: miRNA-1972 is a strong prognostic marker in non-viral HCC. Dysregulation of several other miRNAs relates to pathological variables such as amount of stroma within tumor, microvascular invasion and micronodularity.
