Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Precision Strategy (PS) | Participants in the PS group with a PROMISE minimal risk score (PMRS - validated tool) threshold value of greater than 0.46 were assigned to deferred testing. All other participants in the PS group (ie, those with a PMRS \<0.46), or those with known atherosclerosis such as vascular calcification on chest CT, received cCTA with selective FFR-CT for site-read 30% to 90% stenoses.~All PS and UT testing was performed according to local protocols, and all subsequent testing and care decisions were made locally. | 40 | 1,057 | EG000 |
| Group 2 | Usual Testing (UT) | Among participants in the UT group, site clinicians chose the initial testing modality, including exercise electrocardiogram, stress echocardiogram, stress nuclear myocardial perfusion imaging (single-photon emission CT or positron emission tomography), stress cardiovascular magnetic resonance imaging, or catheterization.~All PS and UT testing was performed according to local protocols, and all subsequent testing and care decisions were made locally. | 30 | 1,046 | EG001 |
