Figure 3.

Box plot chart comparing normalized feature values for malignant and benign groups across four clinical and ultrasound features: maximum lesion diameter, CEUS base width, TG, and HDL-C. Malignant data are represented in pink, benign in blue. Values for maximum lesion diameter and HDL-C show the most separation between the two groups. Y-axis ranges from negative one to one.

Clinical and ultrasound features by lesion pathology: boxplots show the distributions of maximum lesion diameter, CEUS-derived base width, triglyceride, and high-density lipoprotein cholesterol. The actual feature names are displayed directly on the x-axis, and the y-axis represents normalized values. Benign and malignant indicate histopathologically confirmed benign and malignant lesions, respectively. CEUS, contrast-enhanced ultrasound; TG, triglyceride; HDL-C, high-density lipoprotein cholesterol.
