Registered outcomes 5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | d2 Test of Attention - Concentration Performance (CP) | Baseline and post-intervention at week 12 | Concentration Performance (CP) is calculated as the number of correctly crossed-out target items minus the number of commission errors (E2). It reflects the participant's selective attention and concentration capacity. Higher scores indicate superior attention performance. | ClinicalTrials.gov |
| Secondary | d2 Test of Attention - Total Number of Items (TN) | Baseline and post-intervention at week 12 | The Total Number of Items (TN) score represents the total number of characters processed, serving as a quantitative measure of visual scanning speed, workload capacity, and raw processing speed. | ClinicalTrials.gov |
| Secondary | d2 Test of Attention - Total Number of Items Minus Errors (TN-E) | Baseline and post-intervention at week 12 | The TN-E score is calculated as the total number of items processed minus the sum of errors. It represents a comprehensive baseline and post-intervention metric for overall attention performance. | ClinicalTrials.gov |
| Secondary | d2 Test of Attention - Fluctuation Rate (FR) | Baseline and post-intervention at week 12 | The Fluctuation Rate (FR) score is calculated as the difference between the maximum and minimum number of items processed per line. It provides a measure of attentional stability, consistency, and pacing throughout the test. | ClinicalTrials.gov |
| Secondary | d2 Test of Attention - Error Percentage (TN-E%) | Baseline and post-intervention at week 12 | The Error Percentage (TN-E%) provides a measure of accuracy, carefulness, and qualitative control during the attention task. | ClinicalTrials.gov |
