Table 11_Association between the aMAP risk score and mortality in the MASLD/MetALD/ALD pat

32,654 participants from the U.S. National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 were analyzed to assess the aMAP risk score's link to mortality. The study, authored by Peng-yang Li and last updated in 2026, found the aMAP score is independently associated with higher all-cause, cardiovascular, and cancer mortality across steatotic liver disease subgroups. An external validation cohort of 642 Southern Chinese patients was also included.

Use Cases

• Validate the aMAP score as a non-invasive mortality risk predictor based on the described cohort study methodology.
• Analyze competing mortality risks (cardiovascular vs. cancer) in liver disease patients based on the Fine-Grey analysis mentioned.
• Assess non-linear relationships between risk scores and outcomes using the restricted cubic spline analysis described.
• Conduct external validation of clinical risk scores using the described independent hospital-based cohort.

Strengths

• Large primary cohort of 32,654 participants from a nationally representative survey (NHANES).
• Includes an external validation cohort of 642 patients for result confirmation.
• Mortality data were linked via the National Death Index through December 31, 2019.
• Analysis covers multiple mortality endpoints: all-cause, cardiovascular, and cancer.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the primary dataset is unknown, which may limit suitability assessment.
• The dataset is very small (19.8 KB), suggesting it may contain summary results rather than raw patient-level data.
