The authors of the above research report have informed the journal that an error occurred during construction of the boxplots shown in Fig 5A. These plots should be replaced by the ones presented here. The original statistical analyses and the p‐values obtained remain valid. Figure 5A now shows that there is a statistically significant correlation between patients' age and expression levels of HP1α. There is no significant association of high HP1α levels with tumor, size, tumor grade or mitotic index.
On page 183, right column, line 27, the statement published should now read:
“We found that high levels of HP1α significantly associate with increased age of the patient (p = 0.0014), but do not associate significantly with tumor size, grade and mitotic index (Fig 5A)”.
On page 183, right column, the last sentence should now read:
“Furthermore, quantitative RT‐PCR analysis carried out for HP1alpha showed significant correlation with the age of the patients and disease outcome.”
Despite these changes, the main conclusions of the article remain unchanged.
