CHG Index Association with Fatty Liver Disease in a Chinese Health Check-up Population

A Chinese health check-up population of 166,647 adults from Chongqing Medical University between July 2022 and March 2025. The dataset likely contains results from a cross-sectional study investigating the association between a novel glucose-lipid metabolic indicator (CHG index) and metabolic dysfunction-associated fatty liver disease (MAFLD). The study was authored by Yunzhen Tang and published on figshare in April 2026.

Use Cases

• Evaluating the discriminative ability of the CHG index for MAFLD based on ROC curve analysis results.
• Investigating nonlinear relationships between metabolic indicators and disease prevalence based on restricted cubic spline analysis.
• Comparing the performance of different metabolic indices (CHG, TyG, FLI) for MAFLD detection.
• Conducting subgroup analyses to assess indicator stability across different demographics like age, sex, and BMI.
• Building logistic regression models to assess risk factors for MAFLD based on the study's methodology.

Strengths

• Includes 166,647 participant records, providing a substantial sample size.
• Contains specific statistical results, such as an AUC of 0.810 for the CHG index and odds ratios for MAFLD association.
• Reports a clear temporal coverage from July 2022 to March 2025.

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 bias inherent to a single-center study in Chongqing, China.
