Scatter plots showing significant causal correlations between various allergic diseases and peripheral blood immune-related cells and hematological traits. A, C Significant causal effects of the ratio of CD4⁺ T/CD8⁺ T cells on asthma and allergic dermatitis, respectively; B significant causal effects of monocytes on BAD; D, E significant causal effects of asthma2018 on total blood hemoglobin and monocytes, respectively; F significant causal effects of shrimp allergy on CD3⁺ T cells. Scatter plots for CD4⁺ T and lymphocyte cells could not be drawn as only one valid SNP in MR analysis
