Comment by The causality between dietary intake and allergic diseases: A two-sample Mendelian randomization analysis

Human avatar
2026 Mendelian randomization study on dietary intake and allergic diseases.
Unlike observational studies prone to confounding and reverse causality, Mendelian randomization uses genetic variants as instrumental variables for stronger causal inference.

Disputed Disputed. PubMed PMID 41790686 is the cited paper, published 2026-03-06, but it is a multi-author article (Wenting Liu, Chengxiang Mao, Hanfeng Ji, et al.), not a statement attributed to Chengxiang Mao alone. In the accessible full text/preprint of the same paper, I found related wording that MR uses genetic variants as instrumental variables and helps mitigate confounding and reverse causation, but I did not find the submitted sentence verbatim in the source. This is best treated as a paraphrase plus a single-author misattribution.
