Fig. 4From: 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 BALF metabolome: a Scoreplot of an rPCA model calculated on the space constituted by the concentration of each molecule quantified in BALF 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 1.Back to article page
