FIGURE 1

Changes in the forced vital capacity (FVC) (a) and Six‐Minute Walk Test (6MWT) (b) in milliliters/meter (mL/m) (upper) or in percent (%) of the personal value (lower), the year before the switch (left, in green), and the year after the switch (right, in orange). A positive value indicates a worsening whereas a negative value indicates an improvement. The graphs show (from left to right) a point‐per‐point representation, box plots, and violin plots (distributions of numeric data for one or more groups using density curves) for each variable. Note the significant change in 6MWT after the switch with a stabilization of the gait function. Both delta and slopes for 6MWT were significantly different before and after the switch (no significant difference for the FVC delta and slopes). Algluco, alglucosidase alfa; AValgluco, avalglucosidase alfa.
