About CBAR

The Canadian Biliary Atresia Registry (CBAR) is a collaboration between the Canadian Pediatric Hepatology Research Group (CPHRG) and the Canadian Association of Pediatric Surgeons (CAPS), the two well-established networks in Canada involved with the care of children with biliary atresia.
