The association between dietary isoflavones intake and gastric cancer risk: a meta-analysis of epidemiological studies
Abstract Background Isoflavones, a class of phytoestrogenic compounds, are abundant in soybeans. A number of epidemiological studies have investigated the association between dietary isoflavones intake and the risk of gastric cancer. However, the results are inconclusive. Therefore, the meta-analysi...
