Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Diagnostic accuracy of the OCS: the ability of the OCS to identify cognitive impairments in the subacute and chronic stage after stroke | From enrolment in the subacute stage (max three weeks post-stroke) to assessment in the chronic stage (6-9 months post-stroke). | Diagnostic accuracy will be evaluated in both the subacute and the chronic stage. First, agreement between impairment classifications using the OCS and impairment classifications on matched comprehensive neuropsychological tests will be quantified using Cohen's kappa coefficients. Second, diagnostic accuracy will be assessed by estimating sensitivity and specificity of OCS in relation to the matched comprehensive neuropsychological test battery. Impairment on a test is determined using cut-offs provided in test manuals when available or using norm-based cut-offs set at 1,5 standard deviations bellow the mean (or equivalent). |
| Secondary | Predictive validity of the OCS: the ability of the OCS in the subacute stage to predict cognitive performance on a detailed neuropsychological test battery in the chronic stage. | From enrolment in the subacute stage (max three weeks post-stroke) to assessment in the chronic stage (6-9 months post-stroke) | Association between performance on the OCS in the subacute stage and performance on a full neuropsychological test battery in the chronic stage measured using logistic regression models. |
| Secondary | Prevalence of cognitive impairments in the subacute and the chronic stage after stroke | From enrolment in the subacute stage (max three weeks post-stroke) to assessment in the chronic stage (6-9 months post-stroke). | Prevalence estimates will be based on impairment classifications derived from the comprehensive neuropsychological battery in the subacute and the chronic stage respectively. Impairment on a test is determined using cut-offs provided in test manuals when available or using norm-based cut-offs set at 1,5 standard deviations bellow the mean (or equivalent). |
