The result showed that after removing Zhu ZS's study, Wang J’s study, Li CY’s study, or Zhu J’s study, no significant association was found between EGLN2 rs10680577 polymorphism and cancer risk under recessive genetic model (Table 3), suggesting that results of the overall pooled analysis were not sufficiently robust under recessive genetic model, which might be due to the small number of studies and needed to be further confirmed by large‐scale and well‐designed case–control studies. Here, EGLN2 is linked to cancer.
