6MWT indicates 6-minute walk test; high, a starting dose of 2.0 mg/kg/d or greater; low, a starting dose of less than 2.0 mg/kg/d; points, means; whiskers, standard error of the mean. Mean estimated differences between participants treated at higher dose and low dose, as well as P values, are provided at 6 months (ie, prior to LTE) and 30 months (ie, at conclusion of LTE).
