Fig. 1From: Genome-wide DNA methylation study of hip and knee cartilage reveals embryonic organ and skeletal system morphogenesis as major pathways involved in osteoarthritisMultiple dimensions scaling of hip OA, knee OA, and OA-free hip cartilage. *Similarities between hip OA, knee OA, and OA-free cartilage, drawn from log-spectral decompositions for each subject as represented in the two-dimensional space by multiple dimensional scaling (MDS). Each dot represents one sample. Colors represent the type of involvement and the site samples obtained. X- and Y- axes represent the first and the second dimension reductionsBack to article page
