Fig 4. Scatter dot plot showing individual histopathology scores using the modified scoring system (SS) compared with a second scoring (SS) eight months later (n = 35).

This was to calculate the Intra-observer repeatability of the modified histopathology scoring system. Kendall rank order coefficient T = 0.88, z = 7.44, p≤0.00003. NB some similar values that overlapped have been nudged so that the data points can be seen.
