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
IntroductionGiven the importance of early renal cancer diagnosis and the limitations of conventional imaging assessment, ultrasound radiomics has emerged as a promising non-invasive technique for differentiating benign from malignant renal masses. This meta-analysis is aimed to assess the ability of ultrasound radiomics in differentiating benign and malignant renal masses.Materials and MethodsLiterature was systematically retrieved from the inception of the databases to April 27, 2025. Meta-analysis was conducted using Review Manager, Meta-Disc, and STATA software to calculate pooled diagnostic accuracy metrics. Sensitivity analysis and subgroup analysis were performed to explore the sources of heterogeneity. Deeks' funnel plot was adopted to evaluate publication bias, and the Fagan nomogram was applied to assess clinical utility.ResultsThis study included 7 articles comprising a total of 1,864 cases (1,166 malignant and 698 benign). The pooled sensitivity, specificity, and AUC of ultrasound radiomics for differential diagnosis of benign and malignant renal masses were 0.83 (95% CI, 0.81-0.86), 0.79 (95% CI, 0.69-0.87), and 0.84(95% CI: 0.81-0.87). Significant heterogeneity was observed in pooled specificity among the 7 included studies. Subgroup analysis revealed that mass size and feature extraction software type contributed to the heterogeneity of specificity. Accordingly, 5 studies of simple small renal masses were further analyzed. The pooled sensitivity, specificity, and AUC of ultrasound radiomics for differential diagnosing of benign and malignant small renal masses were 0.84 (95% CI, 0.80-0.87), 0.72 (95% CI, 0.64-0.79), and 0.85(95% CI, 0.82-0.88). Fagan nomogram demonstrated a 30% increase in post-test probability for patients with positive pre-test results and a 15% decrease for those with negative pre-test results, indicating moderate clinical utility of radiomics.ConclusionUltrasound radiomics has favorable value in the differential diagnosis of benign and malignant renal masses, and is expected to serve as a reliable auxiliary tool for clinical preoperative diagnosis.
