The difference in erosion and JSN for mTSS, jointly or separately, between the two sides is shown for right-handed and left-handed patients. The blue line shows the zero point. The score differences were assessed by Student t-test. X-axis: The differences in mTSS or its component between the two sides (the right-side score minus the left-side score). Y-axis: The number of patients. The red line indicates the mean value. (a) Upper + Lower extremities (b) Upper extremities (c) Lower extremities.
