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

357 participants underwent three non-invasive liver fat quantification techniques: Liver Steatosis Analysis (LiSA), Ultrasound-Guided Attenuation Parameter (UGAP), and Controlled Attenuation Parameter (CAP). The dataset, authored by Juan Chen and last updated in March 2026, contains results from a prospective comparative study evaluating the diagnostic performance of LiSA and UGAP against the CAP reference standard.

Use Cases

• Compare diagnostic performance of LiSA and UGAP based on correlation coefficients and AUROC values mentioned in the description.
• Validate proposed cut-off values for steatosis grades based on the CAP-referenced suggestions for LiSA.
• Assess technical success rates of different ultrasound attenuation techniques based on the reported IQR quality control metrics.

Strengths

• Includes data from 357 participants, providing a substantial clinical sample.
• Reports strong correlation coefficients (r=0.83 for LiSA, r=0.81 for UGAP) with the reference standard.
• Provides specific Area Under the ROC Curve (AUROC) values for three steatosis grades for both techniques.

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 geographic/temporal bias inherent to the single study source.
