Following publication of the original article [1], the authors flagged that the article had published with an error in ‘Table 1’.

Table 1.

General parameters of PND60 mice treated with neonatal hyperoxia

Parameter		N		mH		sH

Lung values
lung-to-body weight b	(·10−3)	1.29	± 0.28	1.28	± 0.26	1.37	± 0.28
lung wet-to-dry weight b		8.32	± 1.43	7.84	± 1.66	8.80	± 1.38

BAL IgM b	(ng∙ml−1)	15.1	± 13.1	16.0	± 9.50	18.9	± 14.7

Data are means ± SD with *P < 0.05 vs. N group

^an = 80 in N group, n = 50 in mH group, n = 40 in sH group

^bn ≥ 28 each group

^cn = 17 each group. The respiratory function is more challenged by faster than slower running speeds. As female mice run faster and reach higher running distances than male mice [20], we only studied females

^dCytological investigations showed alveolar monocyte-like cells as major cell type (80%) followed by differentiated macrophages (19%), granulocytes (0.8%) and lung epithelial cells (0.2%). The relative quantity of these cell types was not altered in the mH or sH group

The error was that in the row PND60-survival^a the value ‘80’ was erroneously repeated, and the special symbol (*) contained in the value ‘68*’ was erroneously repeated after the value.

Table 1 has now been corrected in the published article.
