Figure 1From: Matrix metalloproteinase protein expression profiles cannot distinguish between normal and early osteoarthritic synovial fluid Comparison of MMP protein expression within the synovial fluid of Normal (n = 25), Early OA (n = 12), advanced OA (OA) (n = 17), and RA (n = 15) patients. Significant differences indicated by bars connecting treatment groups. Box and whisker plot using Tukey’s method, individual dots represent outliers.
