Fig 5. Cumulative probability plots regarding longitudinal changes in each erosion parameter for patients with RA.
Each absolute least significant change (LSCSD) is shown as a broken line. Plots exceeding the LSC indicate significant changes on both positive and negative sides. (Er.V, erosion volume; Er.D, erosion depth in the axial view; Er.D-2, erosion depth in the perpendicular (coronal or sagittal) view; Er.W, erosion width in the axial view; Er.L, erosion length in the perpendicular view; Er.BMD, peripheral bone mineral density surrounding an erosion).
