A  meta-analysis of the association between poultry and egg consumption and the risk of brain cancer.

The objective of this meta-analysis is to investigate the role of poultry and egg consumption for brain cancer risk. All articles about poultry and egg consumption for brain cancer were retrieved from PubMed, Web of knowledge and Wan Fang Med Online. The data was analyzed using Stata 12.0 software. Ten articles (6 articles for poultry and 5 articles for egg) were included. For poultry consumption, the summarized relative risk (RR) was 0.901 (95%CI= 0.703-1.154) for brain cancer risk, with high between-study heterogeneity (I2= 60.7%, P=0.018). Four studies reported the association between poultry consumption and glioma risk, yielding a RR of 0.873 (95%CI= 0.737-1.034, I2= 0.0%, P=0.838). The association between egg consumption and brain cancer risk was not significant (RR= 0.998, 95%CI= 0.552-1.805), with significant heterogeneity (I2= 82.6%, P< 0.001). The pooled RR for glioma risk was 1.472 (95%CI= 0.935-2.316). In summary, our results concluded that poultry and egg consumption may be not associated with the risk of brain cancer. Due to the limited quality of evidence currently available, more studies related to poultry and egg consumption for brain cancer is necessary. PMID: 30782302 [PubMed - in process]
