Specialist A B C D E Average MAE
A - 10.37 6.04 4.19 10.49 7.52
B 10.37 - 7.33 9.45 6.52 8.17
C 6.04 7.33 - 5.69 7.49 6.39

Abbreviation: MAE, mean absolute error.

For every image, we calculated the absolute error between each specialist’s lesion counts and then averaged the results. The last column is the average of each specialist.
