Diagnostic Performance of CAP for Grading Hepatic Steatosis in a Chinese MASLD Cohort

120 participants, including 17 healthy controls and 103 patients with metabolic dysfunction-associated steatotic liver disease (MASLD), were assessed using MRI-PDFF and transient elastography. The dataset, authored by Siying Wang and last updated in May 2026, contains results evaluating the controlled attenuation parameter (CAP) for grading steatosis severity. It includes diagnostic performance metrics such as area under the curve values and optimal CAP cut-offs with confidence intervals.

Use Cases

• Validate non-invasive steatosis grading tools based on CAP cut-off values.
• Train machine learning models for liver disease classification using the reported diagnostic performance metrics.
• Benchmark transient elastography results against MRI-PDFF as a reference standard.
• Study correlations between clinical parameters and steatosis severity in a MASLD cohort.

Strengths

• Includes data from 120 participants with clear stratification into steatosis grades (S0=17, S1=20, S2=59, S3=24).
• Reports specific diagnostic performance metrics, including AUC values (e.g., 0.947 for ≥S2) and CAP cut-offs with 95% confidence intervals.
• Uses a recognized non-invasive reference standard (MRI-PDFF) for validation.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data is from a single-center retrospective study, which may limit generalizability.
• The dataset is very small at 20.9 KB, indicating limited scope.
