Figure 4

Group 1 Cluster Analysis and PCA demonstrates two subgroups. (A) Heatmap showing the reactivity to the SARS-CoV-2 antigens. Samples were clustered using the hierarchical clustering analysis. The dendrogram was cut (and color coded) to a final cluster number equal 3. On (B), a bar graph showing the mean reactivity and the standard error of each cluster to each individual SARS-CoV-2 antigen. (C) PCA analysis showing the spatial distribution of the samples classified as 1.1 and 1.2 for the first and second principal components. This figure was generated using the R programing language, version 4.0.2 (https://www.r-project.org/).
