To further investigate the connections between m6A modification, VCAM1 expression, and immune infiltration, we utilized the ssGSEA method to calculate pathway enrichment scores in each sample and then identified significant differentially enriched pathways (with threshold: log2FC > 1 or < 1 and p-value < 0.05) between HF samples and normal samples and between high and low VCAM1 expression groups. This evidence concerns the gene VCAM1 and hydrops fetalis.
