A Reproducible MRI-Based Quantitative Feature for Differentiating Dysplastic Nodules from Hepatocellular Carcinoma: A Multicenter Retrospective Study.
Article in Journal of hepatocellular carcinoma, 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
Purpose: High percentage of well-differentiated hepatocellular carcinoma (HCC) was radiologically misdiagnosed as dysplastic nodule (DN), which may lead to delay in treatment. This study aims to develop a reproducible feature for DN/HCC differentiation. Patients and Methods: This study included patients which underwent curative hepatectomy or biopsy from four hospitals in China. The study population was divided into internal training cohort, internal test cohort, external validation cohort. Energy value was extracted from arterial and hepatobiliary phase lesion to represent intensity. Hepatobiliary-Arterial Intensity Ratio (HAIR) was calculated to demonstrate the intensity change from cirrhotic nodule to HCC. GPC3 (Glypican-3) was analyzed to validate HAIR's relation with nodule differentiation. Supporting Vector Machine (SVM) was built as a comparative model. Area Under the Curve (AUC) was used to evaluate and compare the predictive efficacy of HAIR. Results: A total of 116 patients with 120 lesions (52 dysplastic nodules and 68 hepatocellular carcinomas) were included. The AUC of HAIR and SVM for differentiating DN and HCC in internal test cohort were 0.824 (95% CI, 0.662-0.986, Conclusion: HAIR based on arterial and hepatobiliary phase provides a quantitative, reproducible and interpretable tool for DN/HCC differentiation.
