Core Tip
Core tip: The analysis by Lee et al in the paper has some limitations that must be pointed out. The severity of folate deficiency, replacement strategies, and probable vitamin B12 deficiencies should have been discussed. The paper does not do enough to accurately conclude a relationship between folate deficiency and gastric cancer severity.
