Crucially, we identified ethnic-specific thresholds for Chinese populations (CAP: 46.38; LSM: 49.49) that are significantly lower than Western cohorts, characterized by rapid pre-threshold risk escalation and post-threshold plateaus. The strongest correlations appeared in males, the elderly, and non-obese individuals. Sensitivity analyses using multiple imputation showed materially consistent results. In addition, comparative analyses indicated that the ZJU index had generally comparable discriminatory performance compared to conventional indicators, outperforming several metabolic markers for fibrosis-related outcomes, although body mass index (BMI) and waist circumference showed slightly higher area under the curve (AUC) values in some fibrosis models.<\/jats:p>\n
