Relationship of immune cell infiltration and key COVID-19-related KD hub genes. (a) Proportions of 22 types of immune cells in each sample of the GSE100154 dataset (KD vs. control). (b) Proportions of 22 types of immune cells in each sample of the GSE225220 dataset (COVID-19 vs. control). (c) Infiltration status of immune cells in the two groups of the GSE100154 dataset. (d) Infiltration status of immune cells in the two groups of the GSE225220 dataset. (e) Correlation of DEFA4, PGLYRP1, and RETN with infiltration of different immune cells in the GSE100154 dataset. (f) Correlation of DEFA4, PGLYRP1, and RETN with infiltration of different immune cells in the GSE225220 dataset. *p < 0.05; **p < 0.01; ***p < 0.001
