Participant Flow
Subjects will be referred for non-invasive and/or invasive testing and evaluation. Prior to treatment of each subject considered for percutaneous coronary intervention (PCI) and/or coronary artery bypass grafting (CABG), the investigator and the institution's heart team will review clinical data and results of the diagnostic tests to recommend a treatment strategy, according to the institution's standard practice.
Patients were eligible for enrollment if they were symptomatic, had an intermediate likelihood of CAD, did not have an established diagnosis of CAD, and were referred for clinically indicated testing to evaluate CAD. Patients referred for noninvasive testing were enrolled in a separate stratum than patients referred for invasive testing. The choice to refer the patient for invasive testing rather than noninvasive testing was made by the local clinicians before enrollment in the study.

SECONDARY outcome
Timeframe: 90 days from first testPopulation: The analysis population was defined as all subjects who were enrolled into the study. Safety was monitored throughout the study. The low number of MACE events made it impossible to analyze the powered secondary endpoint. None of the events were related to the FFRCT.
90 days (+30/-30 days) Cohort 1 and Cohort 2 Major Adverse Coronary Event (MACE) rates, defined as: 1. All cause death 2. Non-fatal MI 3. Unplanned hospitalization for acute coronary syndrome (ACS) leading to urgent revascularization

Timeframe: 90 days from first testPopulation: The analysis population was defined as all subjects who were enrolled into the study. It is important to note that none of the adverse events reported throughout the study were related to FFRCT.
90 days (+30/-30 days) Major Adverse Coronary Event (MACE) rates, defined as: all cause death, non-fatal MI, unplanned hospitalization for acute coronary syndrome (ACS) leading to urgent revascularization and vascular complications (related to any coronary testing or procedure).This secondary endpoint compared the rates of MACE and vascular events across all subjects in Cohort 1 vs Cohort 2, Cohort 1A vs Cohort 2A and Cohort 1B vs Cohort 2B. The rates of MACE and vascular events were calculated by dividing the number of subjects with MACE and vascular events by the total number of subjects assigned to each analysis population.
