Intervention 1 had fewer cardiologists (24.3%) compared to the other arms (38.8% and 36.5% for control and intervention 2, respectively); control were slightly older than either intervention arm (58.4 years for control versus 55.1 years for intervention 1 and 56.9 years for intervention 2); but these did not achieve significance (p > 0.05 for both).
