  1. 01HumanRandomized controlled trialEfficacy outcome

    In young children with achondroplasia, vosoritide exceeded placebo in height Z-score change by 0.25 (95% CI -0.02 to 0.53).

    In plain wordsIn young children with achondroplasia, height score change favored vosoritide over placebo, but the confidence interval included zero.
