Figure 4. Mean change from baseline in compound muscle action potential (CMAP) amplitude, CMAP area, and motor unit number estimation (MUNE) value.

Figure 4

(A) CMAP amplitude, (B) CMAP area, and (C) MUNE value. Due to the gap between CS2 and CS12 and windowing of visit days, some windowed visits do not contain all children. SE = standard error; SMA = spinal muscular atrophy.
