Development and validation of pFIB scores for exclusion of significant liver fibrosis in pediatric MASLD.

Analyzing several cohorts totaling approximately 1100 children and adolescents, we developed novel risk scores incorporating readily available clinical variables. In accordance with the aim of excluding pediatric MASLD-associated fibrosis, the scores performed better in nonselected cohorts of children and adolescents living with obesity than in patients referred to tertiary liver units.
