High-frequency contrast-enhanced ultrasound in discriminating benign and malignant superficial lymph nodes: a diagnostic comparison.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundLymph nodes are critical immune system components, filtering harmful substances and acting as indicators in various disease states, including cancer. Accurate differentiation between benign and malignant superficial lymph nodes is essential for diagnosis and treatment planning. However, conventional diagnostic methods often lack the required precision. High-frequency contrast-enhanced ultrasound (H-CEUS) offers improved temporal resolution and visualization of microvascular structures, potentially providing better diagnostic accuracy than standard contrast-enhanced ultrasound (CEUS).
methodsThis study included 77 patients with suspected abnormalities in superficial lymph nodes. Each patient underwent H-CEUS and CEUS examinations, with diagnoses confirmed through biopsy or surgical resection. The diagnostic performance of H-CEUS and CEUS was evaluated using sensitivity, specificity, positive predictive value, negative predictive value, and accuracy. Chi-square tests and ROC curve analysis were employed to compare the efficacy of H-CEUS and CEUS in differentiating benign from malignant lymph nodes.
resultsH-CEUS demonstrated superior diagnostic performance over CEUS, with higher sensitivity (95.92% vs. 83.67%), specificity (92.86% vs. 57.14%), and accuracy (94.80% vs. 74.03%). H-CEUS enhanced microvascular morphology visualization, facilitating more accurate differentiation between benign and metastatic lymph nodes. The area under the ROC curve for H-CEUS (0.944) was significantly greater than that for CEUS (0.704), indicating improved diagnostic capability.
conclusionH-CEUS offers enhanced accuracy in diagnosing the nature of superficial lymph nodes, potentially improving clinical decision-making for patients with suspected lymph node malignancies. These findings support the integration of H-CEUS into routine clinical practice to achieve better diagnostic outcomes.
