Fig. 5From: Respiratory metabolites in bronchoalveolar lavage fluid (BALF) and exhaled breath condensate (EBC) can differentiate horses affected by severe equine asthma from healthy horsesRobust Principal component analysis of the EBC metabolome: a Scoreplot of an rPCA model calculated on the space constituted by the concentration of each molecule quantified in EBC samples. Empty circles highlight the median values for asthma a and control c groups. b Bar plot describing the correlation between the concentration of each molecule and its importance along PC 1Back to article page
