Fig. 3

Comparison of EIM data at selected frequencies (30, 50, 100, and 300 kHz) between WT (black circle, n = 6) and mdx (red square, n = 6) mice in a natural history study from 6 to 24 weeks of age. The EIM data are shown as three major parameters of reactance (top row), resistance (middle row), and phase (bottom row). Data at selected frequencies from Fig. 2 are plotted as mean ± SEM. Statistical comparisons between WT and mdx mice were performed retroactively from the endpoint at 24 weeks of age until no significant difference was detected (Student’s t-test, ^*p < 0.05, ^**p < 0.01, ^***p < 0.001). EIM: electrical impedance myography, WT: wild-type, SEM: standard error of the mean
