LiSA and UGAP vs CAP: Diagnostic Performance for Liver Steatosis in 357 Patients

357 participants underwent three non-invasive liver fat quantification techniques in a single-visit prospective study. The dataset compares the diagnostic performance of Liver Steatosis Analysis (LiSA) and Ultrasound-Guided Attenuation Parameter (UGAP) against the Controlled Attenuation Parameter (CAP) reference standard. It was authored by Juan Chen and uploaded to figshare in March 2026.

Use Cases

• Compare diagnostic accuracy of LiSA and UGAP based on AUROC values for different steatosis grades.
• Validate suggested cut-off values for LiSA (269.00 dB/m and 300.00 dB/m) for diagnosing moderate and severe steatosis.
• Analyze correlation between attenuation parameters and Body Mass Index (BMI) based on Pearson correlation analysis.
• Assess technical success rates of different ultrasound-based steatosis quantification methods.

Strengths

• Includes data from 357 participants, providing a substantial clinical sample.
• Reports very high technical success rates for LiSA and UGAP (both 99.74%).
• Provides specific AUROC values (e.g., 0.96 for ≥S1) and correlation coefficients (r=0.83) for performance comparison.
• Study followed standardized protocols with strict quality control (IQR <40 dB/m, IQR/M <30%).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and source bias inherent to a single prospective study.
