Cereal or Grain Consumption and Gastric Cancer Risk: a Systematic Review and Meta-analysis of Observational Studies

This project involved a systematic literature review of published trials of cereal or grain in relation to the risk of gastric cancer. Data was extracted from the publications on PubMed, EMBASE, Cochrane Library.A traditional meta-analysis, subgroup analysis, and heterogeneity was conducted on the extracted data.

Detailed Description

Investigators searched PubMed, EMBASE, Cochrane Library for studies focusing on cereal or grain in relation to the risk of gastric cancer up to October 2017. Summary odd ratios (OR) and 95% confidence intervals (CI) were calculated by using either random effect models or fixed effect models according to the heterogeneity of included studies. Subgroup analysis, heterogeneity, and publication bias were also performed.
