Ethics approval and consent to participate
: Ethics approval was obtained from the Children’s Mercy IRB at Children’s Mercy Hospital in Kansas City, Missouri under IRB protocol # 15100478. The need for consent was waived by this IRB because the project was a retrospective chart review and final data set did not include any Protected Health Information (PHI). All treatments (ursodiol and phenobarbital) were considered standard care for cholestasis.
