Relationship between Investigative Biomarkers and Radiographic Grading in Patients with Knee Osteoarthritis
Principal component analysis coefficients of independent molecular marker factors
in plasma from 63 patients with knee OA. Molecular markers were grouped into
factors of related measures by principal component analysis using a Varimax
rotation with Kaiser Normalization. Components with Eigen values 1 were
extracted. Primary components of each factor are shown in bold type.
