Registered outcomes 4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Change in MoCA total score | Baseline, 1 month, 3 months, and 6 months after surgery/follow-up | Change in the Montreal Cognitive Assessment total score from baseline to 6 months after surgery/follow-up. In the cohort component, between-group differences and repeated-measures trends are compared between the surgical and non-surgical cohorts. In the case-control component, baseline differences between cases and healthy controls are compared. | ClinicalTrials.gov |
| Secondary | IJV stenosis improvement rate | Baseline, 1, 3, and 6 months after surgery/follow-up | Imaging-based quantitative assessment of improvement in IJVS severity by CTV/ultrasound. | ClinicalTrials.gov |
| Secondary | Head and neck venous outflow patency | Baseline, 1, 3, and 6 months | CTV/MRV assessment of venous sinus morphology, patency, and collateral circulation; ultrasound assessment of blood flow velocity and reflux. | ClinicalTrials.gov |
| Secondary | Incidence of postoperative complications/adverse events | Intraoperative period through 6-month follow-up | Bleeding, infection, hematoma, nerve stimulation, venous thrombosis, contrast agent reactions, etc. | ClinicalTrials.gov |
