Oxidative metabolic activity of sputum samples from 16 CF and 8 control subjects. a Average well color density (AWCD) of metabolic activity corrected for starting bacterial density. P value was obtained using the Wilcoxon-Mann-Whitney rank sum test. b Corrected group well color density values of individual carbon source and antibiotic assays in CF and control samples. P values were generated using the Wilcoxon-Mann-Whitney rank sum test. Only significant values (<0.05) are displayed. c Principal component analysis of corrected AWCD in the presence of carbon sources in both sets of subjects. d Principal component analysis of corrected AWCD in the presence of antibiotics in both sets of subjects. Only modest separation between CF and control samples is noted in both PCA plots
