In the original publication of the article [1], we noticed an error to Table 2. The numbers for each ARHI staining in the subtypes of JMJD2A were mistakenly copied from another molecular which we were simultaneously working on. This mistake went unfortunately unnoticed in the thereafter review and proofreading processes. The Table 2 shown in this erratum is the correct representation of the data from this study. The authors apologize for this error.

Table 2 Association between JMJD2A expression and clinicopathological parameters in 155 cases of breast cancers

As a consequence, the sentence in the left column of Page 6 of 14 of the article PDF, line 4-6, should be accordingly corrected to be “Spearman correlation analysis showed that expression of JMJD2A was inversely correlated with expression of ARHI (p = 0.021, r = -0.185, Table 2)”.
