Fig. 5From: The association between regional transcriptome profiles and lung volumes in response to mechanical ventilation and lung injuryCorrelation matrix and protein interaction network. Pearson correlation coefficient was calculated for the expression of specific pathways in the LPS/MV group (a). Green and red represent negative and positive associations, respectively. The colour intensity corresponds to the magnitude of the correlation coefficient. A protein–protein interaction regulatory network based on these genes was developed (b)Back to article page
