  1. An artifact was labeled as a “definite” microbleed if all three raters agreed that the artifact was a microbleed, and as a “probable” microbleed if two raters agreed that it was a microbleed. This table shows the sensitivity results of the algorithm across these different labels. Note that in a study using only visual ratings, the final column (combining the definite and probable ratings) would be the number typically reported.
