Supplementary file 2_Integrated model based on ultrasound attenuation and metabolic biomar

Supplementary file 2 from a study by Zejun Ma, last updated in May 2026. The dataset likely contains clinical measurements from 172 participants used to evaluate models for non-invasive assessment of hepatic steatosis. The study compared ultrasound attenuation and metabolic biomarkers against quantitative computed tomography-derived fat fraction categories.

Use Cases

• Benchmarking model performance for detecting hepatic steatosis based on ultrasound attenuation values.
• Evaluating the additive value of metabolic biomarkers like ALT and ferritin for disease categorization.
• Training or validating multiclass classification models for hepatic fat fraction categories, with caution for intermediate groups.
• Conducting subgroup analysis based on participant demographics like sex, age, and BMI.

Strengths

• Dataset is associated with a specific study involving 172 participants.
• Model performance metrics, including AUC values with confidence intervals, are reported in the description.
• Data is licensed under CC-BY-4.0, permitting reuse with attribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The study is a single-center cohort from China, which may limit generalizability.
