Aspartate Aminotransferase-to-platelet Ratio Index (APRi) as Biomarker for Liver Damage in Biliary Atresia (BA): A Meta-analysis

Biliary atresia (BA) is a severe paediatric liver disease causing cirrhosis without prompt treatment. Aspartate aminotransferase-to-platelet ratio index (APRi), a non-invasive biomarker, shows promise in assessing fibrosis and cirrhosis severity, offering an alternative to liver biopsy. However, standardised criteria and research on APRi accuracy in paediatric BA, especially across diverse populations, remain limited.
