Two-dimensional score plot of principal component analysis according to pneumonia etiology. Principal component analysis (PCA) was used to identify potentially significant patterns of 65 variables (clinical (n = 8), biological (n = 12), plasma cytokines (n = 30), cytokine production on ex vivo stimulation (n = 15)) from 63 patients with severe pneumonia (non-COVID-19 (n = 36), COVID-19 (n = 27)). Factors 1 and 4 were used to build a two-dimensional score plot of PCA and COVID-19 patients (red circles) and non-COVID-19 patients (bacterial (blue triangles), mixed (blue diamonds), viral (grey crosses) and other non-documented severe community acquired pneumonia (grey Xs)) were represented.
