To the Editor, We thank Zhou et al. for their careful reading of our manuscript and for pointing out an error in the abstract. We agree that the age and gender were not statistically different between the cases and controls. In fact, no statistical comparison was intended, and we did not report any statistical tests in the body of the manuscript or in Table 1. The reference to statistical comparison in the abstract is an editorial error. As Zhou et al. point out, this does not exert any influence on the results or conclusion of our study. We again thank them for raising our attention to this oversight.
