There are errors in the article by Burns et al. (2017).
Following publication of this article, the authors have notified The Journal of an error in two panels of figure 7.
Figure 7. Diaphragm muscle structure.
A, representative images of diaphragm muscle immunofluorescently labelled for laminin from wild‐type (WT) (top left) and mdx (top right) mice. B, representative images of diaphragm muscle immunofluorescently labelled for laminin (green) and myonuclei (blue) from WT (bottom left) and mdx (bottom right) mice. C, group data for coefficient of variation of diaphragm muscle fibre size as measured by minimal Feret's diameter for WT (n = 8) and mdx (n = 8) mice. D, group data for percentage of fibres with centralized myonuclei in diaphragm muscle of WT (n = 6) and mdx (n = 5) mice. Values are expressed as box and whisker plots (median, 25–75% centiles and minimum and maximum values). Data were statistically compared by unpaired Student's t tests. E and F, frequency distribution of WT and mdx diaphragm muscle fibre size as measured by minimal Feret's diameter (E) and cross‐sectional area (F). *** P = 0.0005, **** P < 0.0001 compared with corresponding WT value.

As indicated in the manuscript text, the authors measured minimal Feret's diameter to determine myofibre size. However, in the assembly of the original Fig. 7 the authors displayed co‐efficient of variation of diaphragm muscle fibre size as measured by Feret's diameter (7C) and frequency distribution of muscle fibre size as measured by Feret's diameter (7E). In the revised figure on the following page, the authors have replaced these panels with data related to minimal Feret's diameter, as originally intended and consistent with the text of the manuscript.
The correction has no impact on the conclusions drawn from fig. 7. The data illustrate a left‐shift in the distribution of diaphragm myofibre size in mdx, whether determined from Feret's diameter (shown in the original Fig. 7) or minimal Feret's diameter (shown in the corrected Fig. 7).
There are no changes whatsoever to the conclusions drawn in the manuscript. We apologize to readers.
