Outcome measure score distributions for Readers 1, 2, and 3. Histograms are
organized in columns for different outcome measures (TC, BD, OQ) and in rows for
different readers. Individual histograms depict the number of matched video
pairs in different score categories with SLSC score plotted as a function of
B-mode score. The dashed white lines denote categories in which SLSC and B-mode
scores are the same. Video pairs above this diagonal indicate increase in
outcome measure score from B-mode to SLSC. For each histogram, the percentage of
video pairs with SLSC preference and B-mode preference are indicated in the
top-left and bottom-right corners, respectively.
