Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Difference in Area Under the Receiver Operating Characteristic Curve Between Aortic Size Index and Maximum Aneurysm Diameter | Baseline (at the index presentation for abdominal aortic aneurysm and before any aneurysm intervention) | The discriminatory performance of the Aortic Size Index (ASI) and maximum aneurysm diameter for distinguishing ruptured from intact abdominal aortic aneurysms will be evaluated using receiver operating characteristic curves. The primary measure will be the paired difference between the areas under the receiver operating characteristic curves for ASI and maximum aneurysm diameter. The individual areas under the curves and their paired difference will be reported with 95% confidence intervals estimated using a center-level cluster-aware bootstrap. ASI is calculated as maximum aneurysm diameter in centimeters divided by body surface area in square meters. |
| Primary | Difference in Area Under the Receiver Operating Characteristic Curve Between Aortic Height Index and Maximum Aneurysm Diameter | Baseline (at the index presentation for abdominal aortic aneurysm and before any aneurysm intervention) | The discriminatory performance of the Aortic Height Index (AHI) and maximum aneurysm diameter for distinguishing ruptured from intact abdominal aortic aneurysms will be evaluated using receiver operating characteristic curves. The primary measure will be the paired difference between the areas under the receiver operating characteristic curves for AHI and maximum aneurysm diameter. The individual areas under the curves and their paired difference will be reported with 95% confidence intervals estimated using a center-level cluster-aware bootstrap. AHI is calculated as maximum aneurysm diameter in centimeters divided by height in meters. |
| Secondary | Proportion of Participants With Ruptured Abdominal Aortic Aneurysms Below the Sex-Specific Diameter Threshold | Baseline (at the index presentation for abdominal aortic aneurysm and before any aneurysm intervention) | Among participants with ruptured infrarenal abdominal aortic aneurysms, the number and proportion with a maximum aneurysm diameter below the prespecified sex-specific threshold will be reported with a 95% confidence interval. The thresholds are 55 millimeters for men and 50 millimeters for women. Maximum aneurysm diameter will be measured on the index pre-intervention computed tomography scan. |
| Secondary | Aortic Size Index by Rupture Status | Baseline (at the index presentation for abdominal aortic aneurysm and before any aneurysm intervention) | The Aortic Size Index (ASI), expressed in centimeters per square meter, will be calculated as maximum aneurysm diameter in centimeters divided by body surface area in square meters. ASI values will be summarized using the mean and standard deviation or the median and interquartile range, according to their distribution, and compared between participants presenting with ruptured abdominal aortic aneurysms and participants with intact abdominal aortic aneurysms undergoing repair. |
| Secondary | Aortic Height Index by Rupture Status | Baseline (at the index presentation for abdominal aortic aneurysm and before any aneurysm intervention) | The Aortic Height Index (AHI), expressed in centimeters per meter, will be calculated as maximum aneurysm diameter in centimeters divided by height in meters. AHI values will be summarized using the mean and standard deviation or the median and interquartile range, according to their distribution, and compared between participants presenting with ruptured abdominal aortic aneurysms and participants with intact abdominal aortic aneurysms undergoing repair. |
