Hierarchical cluster analysis of the sIgA targeting. The study participants (columns) and the top-20 nasal bacterial species (rows) were clustered based on the IgA scores, with missing values (when no IgA score could be calculated due to the absence of the species) treated as 0. The proportion of S. aureus reads, sIgA concentration, and CST of the sample, as well as the age and sex of the respective study participant, are displayed at the top. Branches that contain hosts with distinct sIgA targeting profiles are indicated and numbered below. See Figure S4 for the same analysis expanded to all detected nasal bacterial species
