We recently read with great interest an article entitled “Association between exposure to the Chinese famine during infancy and the risk of self-reported chronic lung diseases in adulthood a cross-sectional study, ” by Zhenghe Wang(2017) in BMJ Open 7(5), e015476.The authors examine the association between early-life exposure to the Chinese famine and the risk of chronic lung diseases in adulthood. This study makes a worthy contribution to the area. However, some issues should be taken into account.
In the paper, there are some mistakes in the figure 1 which named “Flowchart on the sample selecting methods at each step”, Combine the context, the number of non-exposed(855)、fetal-exposed(830)、infant-exposed(568)、preschool-exposed(630) groups are wrong in the second line from the bottom. We would like to bring to your attention the errors in methods reported in the aforementioned article.
