Two-dimensional UMAP embeddings: (a) Normal vs. COVID-19; (b) Normal vs. COVID-19 + ${\mathcal{G}}_{\mathit{NC}}$; (c) Normal vs. COVID-19 + ${\mathcal{G}}_{\mathit{NC}}$ + ${\mathcal{G}}_{\mathit{PC}}$; (d) Pneumonia vs. COVID-19; (e) Pneumonia vs COVID-19 + ${\mathcal{G}}_{\mathit{NC}}$; (f) Pneumonia vs. COVID-19 + ${\mathcal{G}}_{\mathit{NC}}$ + ${\mathcal{G}}_{\mathit{PC}}$. Here, G1 and G2 denote ${\mathcal{G}}_{\mathit{NC}}$ and ${\mathcal{G}}_{\mathit{PC}}$, respectively
