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

Juan Chen's 2026 study provides comparative diagnostic performance data for Liver Steatosis Analysis (LiSA) and Ultrasound-Guided Attenuation Parameter (UGAP) against the Controlled Attenuation Parameter (CAP) reference. The dataset includes results from 357 participants, with correlation coefficients, technical success rates, and area under the ROC curve (AUROC) values for different steatosis grades. It also contains suggested cut-off values for LiSA in diagnosing moderate and severe steatosis.

Use Cases

• Compare the diagnostic accuracy of LiSA and UGAP based on the reported AUROC values for different steatosis grades.
• Validate new ultrasound attenuation techniques against the CAP standard using the provided correlation coefficients (r=0.83, r=0.81).
• Establish clinical cut-off values for steatosis grading based on the LiSA thresholds (269.00 dB/m, 300.00 dB/m) suggested in the study.
• Assess the technical feasibility of point-of-care steatosis assessment based on the reported high technical success rates (99.74%).

Strengths

• Includes data from a prospective study of 357 participants, providing a substantial clinical sample.
• Reports specific, high technical success rates for LiSA and UGAP (99.74%) and for CAP (96.84%).
• Provides concrete statistical results, including Pearson correlation coefficients and AUROC values for three steatosis grades.
• Suggests specific diagnostic cut-off values (269.00 dB/m, 300.00 dB/m) for LiSA, referenced to CAP.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (11.9 KB), indicating limited scope, likely containing summary results rather than raw patient-level data.
