Principal component analysis score plot of the discovery data set of P. aeruginosa strains from respiratory chronic infection. Panel (A) shows the average PCA scores from triplicate samples, while panel B displays individual scores for each sample in triplicate. The samples were plotted using principal components 1 and 2 as coordinates. In panel A, Principal component analysis 1 and 2 explain 51.4% and 16.5% of the total variance, respectively; in panel (B), they explain 50.0% and 16.5%, respectively. Identical strains exhibit identical colors in both panels. Isolates IDs are indicated on panel A. Unfilled symbols are used to represent “Early” isolates while filled symbols are used to represent “Late” isolates, corresponding to the first and last available isolate from each patient. LasR+ strains are represented by squares and LasR− strains by circles.
