Participant characteristics. Statistics are presented as mean ± ste, n (%), and median [IQR]. Kolmogorov-Smirnov, Fisher’s exact, and chi-squared tests were performed for continuous (age, total NIHSS) and ordinal (mRS), dichotomous (gender, dominant hand, affected arm, depression, prior stroke, acute stroke therapies, and presence of aphasia, neglect, or sensory deficit), and nominal (ethnicity, antidepressant use, and stroke location) values, respectively.
