Metabonomic-Transcriptome Integration Analysis on Osteoarthritis and Rheumatoid Arthritis

Figure 4

The volcano plot and heat map for correlations between differentially expressed genes and metabolites. (a) The volcano plot: -axis represents the difference in correlation between differentially expressed gene and metabolites; -axis represents the value of correlation. (b) The heat map: OA—the correlation between differentially expressed genes and metabolites in the osteoarthritis group; RA—the correlation between differentially expressed genes and metabolites in the rheumatoid arthritis group; the different colors represent the correlation difference.
