Prediction of brain metastasis in patients with epidermal growth factor receptor-positive lung adenocarcinoma based on lung computed tomography-derived radiomics features.
Article in BMC medical imaging, 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
purposeWe investigated lung computed tomography (CT) radiomics features feasibility for brain metastasis (BM) prediction in patients with epidermal growth factor receptor-positive lung adenocarcinoma (LA-EGFRp).
methodsLung CT images and clinical data of patients were retrospectively analyzed. Patients were classified into BM and non-BM groups, and randomly divided into training and test sets (8:2 ratio). Clinical and CT radiomics features were extracted and trained with various machine-learning classifiers to construct the clinical, radiomics, and hybrid models, respectively. Model performance was assessed using receiver operating characteristic curves.
resultsAmong 198 included patients, 72 developed BM. Areas under the curve (AUCs) for predicting BM in the training and test sets were 0.781 and 0.701, 0.989 and 0.865, and 0.957 and 0.929 for the clinical, radiomics, and hybrid models, respectively. The AUCs of the radiomics and hybrid models were significantly higher in the training set (P < 0.001) and that of the hybrid model in the test set was higher compared with the clinical model (P < 0.05).
conclusionsModels based on clinical data, lung CT-derived radiomics features, and the two combined predicted BM in LA-EGFRp. Combining radiomics and clinical features significantly improved BM prediction, thereby providing an effective tool for clinical decision-making.
