A Corrigendum on
Muscle Twitch Kinetics Are Dependent on Muscle Group, Disease State, and Age in Duchenne Muscular Dystrophy Mouse Models
by Peczkowski, K. K., Rastogi, N., Lowe, J., Floyd, K. T., Schultz, E. J., Karaze, T., et al. (2020) Front. Physiol. 11:568909. doi: 10.3389/fphys.2020.568909
Error in Figure/Table
In the original article, there was a mistake in Figure 3 as published. In Figure 3, the C57 EDL RT50% data (Figure 3A, dataset 8) was erroneously duplicated from the C57 DIA RT50% data (Figure 3A, dataset 4). This mistake happened when we re-made our figures for the final submission. The data in the text, as well as statistics, all outcomes, and all conclusions, are all based on the correct data. The corrected Figure 3 appears below.
FIGURE 3
Figure 3. (A) Time to peak and 50% relaxation of 52 week old dystrophic and wildtype muscle types. Kinetic analysis was conducted in diaphragm and EDL muscles from the same mice. Mouse models include dystrophic MDX and wildtype C57BL/10. Statistical analysis was conducted using a two-sided t-test. **P < 0.01 and ***P < 0.001 compared to C57BL/10 mice. The line represents the group mean; error bars are standard error of mean. (B) 50% relaxation of 52 week old dystrophic and wildtype muscle types. Mouse models include dystrophic MDX and wildtype C57BL/10. Statistical analysis was conducted using a two-sided t-test. **P < 0.01 and ***P < 0.001 compared to C57BL/10 mice. The line represents the group mean; error bars are standard error of mean. (C) Rate constants of individual diaphragm and EDL twitches. Mouse models include dystrophic MDX and wildtype C57BL/10. Statistical analysis was conducted using a two-sided t-test. *P < 0.05, **P < 0.01, and ***P < 0.001 compared to C57BL/10 mice. The line represents the group mean; error bars are standard error of mean.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
