Results along the main diagonal (bold font) show feature value concordance, while the off-diagonal results show the feature value discrepancies.
Discrepancies in abstractor coding of ‘No’ and ‘Not reported’ values for leiomyomas and adenomyosis highlights the possible extent of abstractor inference in the coding of ‘No’ values.
