This article from the February 2018 issue of the European Respiratory Journal was originally published with errors in figure 5b and d. The shaded areas representing statistical significance in these panels were not presented correctly. The corrected figure is presented below, and the original article has been corrected and republished online. No further changes to the body text of the article were needed to address the error.
Evolution with age of the maximum-likelihood estimation population mean curve (thick line) and its 95% pointwise asymptotic confidence intervals (thinner lines) of ribcage volume variations (ΔVRC) and abdominal volume variation (ΔVAB) expressed in litres (a and c, respectively) and as percentage contribution to tidal volume (b and d, respectively) during spontaneous breathing in supine position in DMD patients (black lines) and in healthy controls (grey lines). Light grey areas: values significantly different from predicted with 0.01<p<0.05; dark grey areas: values significantly different from predicted with p<0.01.
