The P value is based on the statistical analysis by the Mann-Whitney U test or unpaired t test according to the characteristics of the data assessing overall group differences and comes from the chronic hepatitis B group and healthy adult group. P1, P2, and P3 values separately denote the significance of comparisons between the treatment-naïve group and Entecavir-treated group, healthy adult group and healthy children group, as well as the treatment-naïve group and healthy adult group.
