The principal component analysis of metabolites and differentially expressed genes. (a) The principal component analysis for differentially expressed genes in transcriptome data. (b) The principal component analysis for metabolites in metabonomic data. The red circles represent osteoarthritis (OA) samples; the blue diamonds represent the rheumatoid arthritis (RA) samples.
