NCT03433092

Brief Summary

Previous studies have suggested that serum carotenoids may be associated with risk of gastrointestinal tract cancer (GIT cancer), but the results were inconsistent. Thus, the investigators conducted a meta-analysis to evaluate the associations between serum carotenoids and risk of GIT cancer.
