Baseline demographics of study participants per group. Numbers in parentheses indicate percentages. Categorical variables are shown as counts and percentages; continuous variables are described using means and SDs. Controls received standard rehabilitation; therefore controls’ “hours of study-specific therapy received” is empty.
