  • Difference of intra-individual change of joint function during each period assessed by the Hemophilia Joint Health Score between on-demand and prophylaxis period
    Hemophilia Joint Health Score(HJHS) ranges from 0 to 124. Higher values in the HJHS represent worse situation for the subject. 2-sided Hodges Lehmann estimates for median 95% CI HJHS values difference of changes ITT analysis set.
