Figure 3 Bland-Altman image of intra-rater credibility and inter-rater credibility of bilateral masseter muscle hardness in stroke patients. The agreement in the hardness value of the bilateral masseter muscle in stroke patients between 2 tests is presented by the mean value of the masseter muscle stiffness (mean value of test for assessor A) for each patient on the affected side (A) and the unaffected side (B). The agreement in the hardness value of the bilateral masseter muscle of stroke patients between different assessors (assessor A and assessor B) is presented by the mean value of the masseter muscle hardness for each patient on the affected side (C) and unaffected side (D). In each Bland-Altman image, the solid line represents the discrepancy of the mean value of the masseter muscle hardness and the dummy lines represent the range of standard deviations.
