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
objectiveTo evaluate the diagnostic value of enhanced computed tomography (CT) radiomics and deep learning in differentiating pediatric peripheral neuroblastoma (NB) from ganglioneuroblastoma (GNB).
methodsRetrospectively enrolled children with pathologically confirmed NB and GNB between February 2014 and December 2024 were randomly sampled and divided into a training set and a validation set. Radiomic features were extracted and selected from arterial-phase and venous-phase CT images. A 3D-UNet model was constructed to train a lesion segmentation model. Radiomic features were automatically extracted and selected from CT images using the 3D-UNet model. Radiomics models and combined models (incorporating clinical indicators) were established on the basis of the optimal feature subsets for the arterial phase, venous phase, arteriovenous phase, and combined clinical data. Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC) was calculated and compared across phases and models.
resultsA total of 225 pediatric patients (161 NB cases and 64 GNB cases) were enrolled. Compared with the radiomic-only models (LDA and LR), the combined models (LDA and LR) incorporating radiomic and clinical features (age and NSE) demonstrated greater diagnostic performance in differentiating NB and GNB. The 3D-UNet-based deep learning model achieved optimal performance after 20 training iterations, with a best Dice coefficient of 0.818 for mixed tumor types in the validation set.The optimal diagnostic performance was achieved by the LR combined model based on venous-phase CT images’ omics features and clinical data (CE2 + C), with an AUC of 0.922 in the training set and 0.913 in the validation set. Both the LDA and LR models exhibited high diagnostic efficacy, with no statistically significant difference (P > 0.05) between the models. There was also no significant difference (P > 0.05) in the diagnostic performance of the combined models across phases when incorporating clinical information.
conclusionEnhanced CT radiomics and deep learning models have significant diagnostic value in differentiating pediatric peripheral NB from GNB.
