Unsupervised principal components analyses (PCA) were performed in R Studio. Complete data were scaled to variance units using
FactoMineR (v2.4 R studio) and the PCA results were extracted and visualized using
factoextra (v1.0.7 R Studio). For
Figures 2,
3, the PCA was performed using all samples data and graphed by days from the onset of symptoms (Early ≤ 43 days; Late > 43 days) for
Figure 2 or by the severity of symptoms (mild or more severe) for
Figure 3. In
Figures 4,
5 the data was divided into two subgroups by the days from the onset of symptoms criteria and then the PCA was performed using severity of symptoms for
Figure 4 or sex for
Figure 5.
