Bi-Regional Machine Learning Radiomics Based on CT Noninvasively Predicts LOX Expression Level and Overall Survival in Hepatocellular Carcinoma.
Article in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveWe aimed to assess the association between lysyl oxidases (LOX) expression levels and the prognosis of patients with Hepatocellular carcinoma (HCC) and to establish a CT-based bi-regional radiomics model that can discriminate LOX expression level using The Cancer Imaging Archive (TCIA) and The Cancer Genome Atlas (TCGA) database.
methods294 HCC samples were downloaded from TCGA for gene-based prognostic analysis. Meanwhile, the underlying molecular mechanism of LOX expression and its relationship with the immune microenvironment was investigated. Thirty-four cases that had preoperative computed tomography (CT) images stored in TCIA with genomic data in TCGA were used for radiomics feature extraction and model construction. The association of this combined LOX-based radiomics model with HCC prognosis was evaluated.
resultsThe expression of LOX in tumor tissue significantly correlated with overall survival (OS). LOX was involved in the regulation of immune response and tumor invasion and metastasis. Two radiomic models were developed using the least absolute shrinkage and selection operator (LASSO) regression analysis. The model of the whole-tumor region has a good predicting effect in LOX expression, with the area under the receiver operating characteristic (ROC) curve being 0.775 in the training set, while the average under the curve (AUC) value of the 5-fold cross-validation was 0.754. The model of the whole-tumor and peri-tumor region also has a good predicting effect in LOX expression, with the area under the ROC curve being 0.800 in the training set, while the average AUC value of the 5-fold cross-validation was 0.796. The calibration curves and the Hosmer-Lemeshow test revealed consistency of the prediction probability acquired by our models and the true value of LOX expression, while the decision curve analysis (DCA) curve showed that both models had clinical practicability.
conclusionLOX expression can influence the prognosis of patients with HCC, which can be predicted noninvasively by CT image-based radiomics.
