Multivariate linear regression analyses of language, speech production and functional performance component scores with respect to potential baseline predictors and early functional performance status. The reference level of effect for Additional disability was 'Absent', and 'Prescription level' was 'DSL'. Values significant at 5% level are marked by asterisks.
