We tested the Spearman correlations of PRAGMA-%Dis and PRAGMA-%Bx with BALF measures (MetO, % OxMet, MPO, total protein), BAL cell populations [percentages of neutrophils (PMNs), macrophages (MΦ), lymphocytes (Lymphs) and eosinophils (Eos)], patient age (months), patient sweat chloride (mM) and the total number of antibiotic courses received by patients in the prior 12 months. (A) Blue-to-red heatmap of Spearman’s ρ for the indicated variables. Red = positive correlation, blue = negative correlation. The intensity of the color indicates the strength of the relationship. (B) Matching single-gradient white-to-red heatmap of p-values (expressed as −log(P)). Intensity of the red color indicates greater statistical significance. Black cells indicate results of p > 0.05 for the relevant pairwise correlation. Cells denoted by (X) indicate where rows and columns for the same variable meet.
