Mean and 95% confidence intervals of four selected upper movement ratios between dominant and non-dominant upper limb movement metrics, rCfe45 (panel a), rCsp45 (b), rDfe45 (c), and rDsp45 (d), stratified by disease onset on non-dominant upper limb (ND), dominant upper limb (D), and neither (N). For count metrics (panels a and b), values greater than 0 indicate a more frequent use of the dominant upper limb; for duration metrics (panels c and d), values greater than 0 indicate faster movements of the non-dominant upper limb. The statistical significance of two sample t-test p-values are denoted as follows: * < 0.05, ** < 0.005, *** < 0.0005
