Summary
Brief summary (as posted)
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.
