Dietary factors and colorectal cancer risk in Asian populations: a systematic review and meta-analysis of cohort studies.

ABSTRACT:

Purpose

Colorectal cancer (CRC) is the third most common cancer worldwide and a leading cause of cancer-related mortality. Few studies have examined the preventive effects of dietary factors against CRC in Asian populations.

Methods

We included cohort studies from PubMed, Web of Science, Embase, and Scopus reporting an association between dietary factors and CRC risk in Asian populations. Relative risks (RRs) with 95% confidence intervals (CIs) were used to calculate the pooled risk estimates. Cochran's Q and I² statistics were employed to a
