BA = biliary atresia; BMI = body mass index; HPE = hepatoportoenterostomy; PHT = portal hypertension.

^*Mean ± standard deviation, number in parenthesis indicates number of subjects with measurement of interest.

^†Weight, height, BMI, arm circumference, triceps skin fold, and subscapular skin fold all expressed as z score for age. No significant differences for any of the comparisons were noted. Note BMI z scores not available at age <2 years.

^‡PHT absent vs PHT possible, significant at α = 0.05.
