Figure 2

Hand tapping as a function of CAG length, age, and sex at baseline (first visit). Older patients and those with a greater number of repeats perform fewer taps. In addition, females perform fewer overall taps than males (p = 0.0001; female plane is shifted downward). Black points on the floor are the locations of the observed data values for age and CAG length. As can be seen, there are no old patients with a high number of repeats.
