Registered outcomes 3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Total Bilateral Jugular Foramen Volume | Single time point per participant, using the index cranial CT acquired between January 2022 and July 2026; retrospective assessment without follow-up. | Total jugular foramen volume (cm³), calculated as the sum of right and left volumes on archived cranial CT images. Each side is estimated using an elliptical-cylinder model: π/4 × mediolateral diameter × anteroposterior diameter × craniocaudal height, with conversion from mm³ to cm³. Measurements are performed by two readers blinded to group assignment, and their mean is used for analysis. Total volume is compared between participants with atrial fibrillation and controls. | ClinicalTrials.gov |
| Secondary | Right and Left Jugular Foramen Volumes | Single time point per participant, using the index cranial CT acquired between January 2022 and July 2026; no longitudinal follow-up. | Right and left jugular foramen volumes (cm³) are assessed separately on archived cranial CT images using an elliptical-cylinder model. Measurements are averaged across two readers blinded to group assignment and compared between participants with atrial fibrillation and controls. | ClinicalTrials.gov |
| Secondary | Discrimination of Atrial Fibrillation by Jugular Foramen Volume | Retrospective assessment using the index cranial CT and rhythm documentation within 12 months of CT; no longitudinal follow-up. | Discrimination between participants with atrial fibrillation and controls is assessed using the area under the receiver operating characteristic curve (ROC AUC), with 95% confidence intervals, for total bilateral jugular foramen volume and its age- and sex-adjusted z-score. | ClinicalTrials.gov |
