Eight non-invasive liver fibrosis indices were calculated based on fasting laboratory parameters obtained within 24 hours of admission. The primary outcomes were HT and sICH. Multivariable logistic regression and restricted cubic spline analyses were performed to assess the associations.Results: Of the 340 patients, 161 (47.4%) developed HT, and 69 (20.3%) experienced sICH. After adjusting for confounders, elevated fibrosis-4 index (FIB-4) (adjusted odds ratio [aOR]=1.25, 95% CI: 1.01– 1.56; aOR=1.48, 95% CI: 1.12– 1.94), the modified FIB-4 (aOR1.07, 95% CI: 1.01– 1.15; aOR=1.13, 95% CI: 1.04– 1.23), the aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AAR) (aOR=1.43, 95% CI: 1.03– 1.96; aOR=1.91, 95% CI: 1.16– 3.12), and the AST to ALT-platelet ratio index (AARPRI) (aOR=1.53, 95% CI: 1.07– 2.17; aOR=2.36, 95% CI: 1.45– 3.84) were independently associated with increased risks of both HT and sICH. Conversely, the FIB-5 index showed an inverse association (aOR=0.95, 95% CI: 0.91– 1.00; aOR=0.91, 95% CI: 0.85– 0.98). These indices demonstrated higher predictive values for sICH (AUC: 0.65– 0.70) than for HT (AUC: 0.61– 0.62). Notably, patients with parenchymal hematoma had significantly greater liver fibrosis indices than those with hemorrhagic infarction or no hemorrhage (all P< 0.05).Conclusion: Non-invasive liver fibrosis indices are independently associated with post-EVT hemorrhagic complications in anterior circulation stroke patients and may serve as readily accessible tools for risk stratification.Keywords: large vessel occlusion, liver fibrosis, hemorrhagic transformation, symptomatic intracerebral hemorrhage, endovascular therapy, stroke
