PRIMARY outcome

Timeframe: From first treatment to the end of treatment (up to 48 weeks) and the end of follow-up (up to 96 weeks)

The number of AEs includes both AEs and Serious Adverse Events (SAEs). The incidence is calculated as the number of AEs divided by the number of person-years of observation, which is the sum, across all participants, of the number of years between the start of treatment and the end of treatment, or the end of follow-up, respectively.

HBV drug resistance variant testing was performed at the CDC laboratory. The sequences of the HBV polymerase spanning nucleotide positions 311-1021 were determined by Sanger sequencing. Drug resistance mutations that were tested in this study included L80VI, L82M, T128N, W153Q, F166L, I169T, V173L, L180M, A181TV, T184ACFGILMS, V191T, A194T, A200V, S202ETV, M204IV, V207I, N236T, M250ILV, and G145R.

A child's Z-score is the number of standard deviations that the child is from the average of children of the same sex and age from a reference population. The reference population is provided in the 2000 Centers for Disease Control and Prevention (CDC) growth charts. Positive Z scores mean the growth measure (weight, height, or body mass index) is above the average, negative Z scores mean the growth measure is below the average.

The Tanner Stage questionnaire is only completed by participants 8 years of age and older. The copyrighted form includes pictures and descriptions. Girls selected the picture closest to their self-perceived breast growth from among 5 stages of breast growth and boys did the same for testes, scrotum, and penis growth. Boys: I-prepubertal; II-enlargement of scrotum and testes; III-enlargement of the penis and further growth of testes; IV- increased size of penis with growth in breadth and development of glans, testes, and scrotum larger, scrotum skin darker; V- adult genitalia. Girls: I-prepubertal; II-breast bud stage with the elevation of breast and papilla and enlargement of the areola; III-further enlargement of breast and areola, no separation of their contour; IV-areola and papilla form a secondary mound above the level of the breast; V: mature adult stage. There is no "better" or "worse" outcome. They are self-assessed descriptive measures of physical growth.

Participants selected the picture closest to their self-perceived pubic hair growth. Boys and girls: I-prepubertal (no pubic hair at all); II-sparse growth of long, slightly pigmented hair, straight or curled, at base of penis or along labia; III: darker, coarser and more curled hair, spreading sparsely over junction of pubes; IV- hair adult in type, but covering smaller area than in adult; V-adult in type and quantity.
