Intra-Articular Synovial Sarcomas: Incidence and Differentiating Features from Localized Pigmented Villonodular Synovitis

Figure 1

One-dimensional PLS-DA score plot showing the separation of the two groups. The color of each dot represents the actual diagnosis of that case, where black corresponds to sarcoma and red to localized PVNS. Green and red horizontal lines correspond to two or three standard deviations (SD) of the vector.
