Figures

FIGURE 1
FIGURE 1
In each plot (A and B), the x‐axis is represented by the grading from Rater A, and the y‐axis is the grading from Rater B for the left (A) and the right forearm (B). Both axes range from 0 to 4. The matrix numbers indicate where Rater A and B provided identical gradings (agreement is marked in green) or different gradings (no agreement is marked in yellow) for the scores. For example, as indicated in (A), Rater A and B assessed the left arm as agreeing with FricTest scores in 11 of 16 patients.
