Mendelian randomization analysis reveals causal relationship between allergic diseases and influenza

The results of this MR study support a causal relationship between allergic diseases, asthma, and influenza, including severe influenza. This finding suggests that allergic diseases and asthma are significant risk factors for influenza. Additionally, this study provides high-quality causal evidence that can inform clinical practices aimed at preventing the onset of influenza, particularly in populations with respiratory allergies and asthma.
