Results of subgroup analysis of the association between nuclear EZH2 expression and OS of multiple cancers.

*: Data regarding treatment were unclear in 16 studies. Further, the treatment in the study of nasopharyngeal carcinoma was radiotherapy, rather than surgery. Accordingly, a subgroup analysis of the treatment was performed after excluding these studies. #: This result was estimated from the fixed-effect model. OS: overall survival; HR: hazard ratio; NSCLC: non-small cell lung cancer. Results of subgroup analysis of the association between nuclear EZH2 expression and OS of multiple cancers.
