§1.3Primary endpoint

Percentage change in body-mass index from baseline to week 68 in adolescents aged 12 to under 18 years

§1.4Principal result

Mean change −16.1 % versus +0.6 % with placebo; estimated difference −16.7 percentage points (95 % CI −20.3 to −13.2).[1]

Growth, bone accrual and pubertal outcomes beyond 68 weeks were not evaluated, which is the Institute’s principal reason for grading this evidence moderate rather than high.

§1.5Provenance of this abstract

Table 1. Field-by-field provenance. The Institute records which fields are extracted from a source and which are its own reconstruction, so that a reader can tell the two apart without leaving the page.
