Registered outcomes41
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change from Baseline of Oculomotor raw performance at 7 years - Latency in Horizontal saccades. | Baseline; Year 7 | This concerns saccades Latency (in ms) during horizontal paradigms. Eye movements were recorded and analyzed with an eye-tracking device. For each subject value were judged abnormal if they differed by \>1.65 SD compared to their reference sample. |
| Primary | Change from Baseline of Oculomotor raw performance at 7 years - Main velocity in Horizontal saccades. | Baseline; Year 7 | This concerns saccades Main velocity (in °/sec) during horizontal paradigms. Eye movements were recorded and analyzed with an eye-tracking device. For each subject value were judged abnormal if they differed by \>1.65 SD compared to their reference sample. |
| Primary | Change from Baseline of Oculomotor raw performance at 7 years - Gain in Horizontal saccades. | Baseline; Year 7 | This concerns saccades Gain (gaze accuracy) during horizontal paradigms. Eye movements were recorded and analyzed with an eye-tracking device. For each subject value were judged abnormal if they differed by \>1.65 SD compared to their reference sample. |
| Primary | Change from Baseline of Oculomotor raw performance at 7 years - Latency in Vertical saccades. | Baseline; Year 7 | This concerns saccades Latency (in ms) during vertical paradigms. Eye movements were recorded and analyzed with an eye-tracking device. For each subject value were judged abnormal if they differed by \>1.65 SD compared to their reference sample. |
| Primary | Change from Baseline of Oculomotor raw performance at 7 years - Main velocity in Vertical saccades. | Baseline; Year 7 | This concerns saccades Main velocity (in °/sec) during vertical paradigms. Eye movements were recorded and analyzed with an eye-tracking device. For each subject value were judged abnormal if they differed by \>1.65 SD compared to their reference sample. |
| Primary | Change from Baseline of Oculomotor raw performance at 7 years - Gain in Vertical saccades. | Baseline; Year 7 | This concerns saccades Gain (gaze accuracy) during vertical paradigms. Eye movements were recorded and analyzed with an eye-tracking device. For each subject value were judged abnormal if they differed by \>1.65 SD compared to their reference sample. |
| Primary | Change from Baseline of Inhibition capacity at 7 years | Baseline; Year 7 | Measure of inhibition capacity performance during an "antisaccades" paradigm. Eye movements were recorded and analyzed with an eye-tracking device. Evaluation criteria: percentage of errors. For each subject value were judged abnormal if they differed by \>1.65 SD compared to their reference sample. |
| Primary | Change from Baseline of Internuclear ophthalmoplegia (INO) detection at 7 years | Baseline; Year 7 | Highlight presence/absence of INO. Eye movements were recorded and analyzed with an eye-tracking device. Evaluation criteria: INO is present if calculated ratio of abducting to adducting eye movement (both mean and peak velocity) is \>1. |
| Primary | Change from Baseline of Fixations impairments detection at 7 years | Baseline; Year 7 | Highlight presence/absence of Fixations impairments. Eye movements were recorded and analyzed with an eye-tracking device. Evaluation criteria: presence/absence/frequency of square wave-jerks, nystagmus, flutters. |
| Secondary | Patients description | Baseline | Profile description of included patients, based on demographic data and clinical exam (sex, age, Weight, height), inclusion/exclusion criteria, medical history, concomitant treatments. |
