Ductular Reaction Underlies Development of Portal Hypertension in Biliary Atresia.

Basic sciencebasic sciencebiomarkerpediatricartificial intelligence
Clinical takeawayNo clinical action yet: a mechanistic finding in pediatric biliary atresia patients. Consider DR% as a potential biomarker for PH risk in future research.
What it foundDuctular reaction (DR%) ≥6.9% at portoenterostomy and ≥3.5% at 1 year predicted portal hypertension (PH) in biliary atresia patients, with AUROC >0.7.
ContextChallenges the current focus on fibrosis as the primary predictor of PH in biliary atresia, suggesting DR% may be a more consistent marker.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
