  1. Descriptive statistics and test results on tremor metrics (mm/s2) for each drawing type and hand, at pre- and post-operative time points. The first row in each Drawing x Hand cell contains the median tremor metrics; the second row contains the first–third quartile range; and the third row is the result of the pre- vs. post-operation tremor metric comparison, which is shown in bold numbers and marked with an asterisk if significant (α = 0.017, p-values uncorrected)
