Determination of pairwise agreement between Pathologists 1 and 2

Pathologist 2 observed result*	Pathologist 1 observed result*
	Agreed with expected result	Disagreed with expected result
Agreed with expected result	Pairwise agreement	Disagreement
Disagreed with expected result	Disagreement	Disagreement

*A single pathologist could report the presence of multiple features in each FOV. The observed result was considered concordant if the selected feature (s) (marked “present”) included the 1-2 features expected to be identified in the FOV. The observed result was considered discordant if one or both of the reported features failed to match the feature (s) expected to be identified in the FOV. FOV: Fields of view
