Association between green tea intake and risk of gastric cancer: a systematic review and dose-response meta-analysis of observational studies.

ABSTRACT:

Objective

To examine and quantify the potential dose-response relationship between green tea intake and the risk of gastric cancer.

Design

We searched PubMed, EMBASE, Web of Science, CBM, CNKI and VIP up to December 2015 without language restrictions.

Setting

A systematic review and dose-response meta-analysis of observational studies.

Subjects

Five cohort studies and eight case-control studies.

Results

Compared with the lowest level of green tea intake, the pooled relative risk (95 % CI) of gastric cancer was 1·05 (0·90, 1·21, I 2=20·3 %) for the cohort studies and the pooled OR (95 % CI) was 0·84 (0·74, 0·95, I 2=48·3 %) for the case-control studies. The pooled relative risk of gastric cancer was 0·79 (0·63, 0·97, I 2=63·8 %) for intake of 6 cups green
