Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Angular Position of the Right Common Carotid Artery Center Relative to the Right Internal Jugular Vein Center | After anesthesia induction and before catheterization | The angular position of the right common carotid artery center relative to the right internal jugular vein center will be determined from standardized transverse ultrasound images. The internal jugular vein center will serve as the reference point, and the angular position will be calculated automatically using image-based coordinate analysis. Each participant will have one angular measurement expressed in degrees (0°-360°). The angular distribution across participants will be characterized using circular statistical methods. |
| Secondary | Distribution of the Right Common Carotid Artery Center Across Eight Anatomical Sectors | After anesthesia induction and before catheterization | The number and percentage of participants whose right common carotid artery center falls within each of eight 45° anatomical sectors relative to the right internal jugular vein center: lateral, anterolateral, anterior, anteromedial, medial, posteromedial, posterior, and posterolateral. |
| Secondary | Circular Descriptive Statistics of the Angular Distribution | After anesthesia induction and before catheterization | The angular distribution will be characterized by the circular mean direction in degrees, mean resultant vector length (R; dimensionless, ranging from 0 to 1), circular standard deviation in degrees, and 95% confidence interval for the circular mean direction. |
| Secondary | Deviation of the Angular Distribution From Circular Uniformity | After anesthesia induction and before catheterization | Deviation of the angular distribution of the right common carotid artery center around the right internal jugular vein center from circular uniformity will be evaluated using the Rayleigh test of uniformity. |
| Secondary | Exploratory Associations Between Patient Characteristics and Angular Distribution | After anesthesia induction and before catheterization | Exploratory analyses will assess associations of age and body mass index with the angular position of the right common carotid artery center relative to the right internal jugular vein center using appropriate circular-linear statistical methods. Differences in angular distribution between sex groups will be evaluated using appropriate circular group comparison methods. |
