Overall performance scores during scenarios of high-fidelity simulation. Points and arrows represent means and standards deviations. We assessed the treatment effect on the primary endpoint (overall performance) using linear regression model including main effects of group (Rb, Bfb + Rb, Control) and scenario, and assessing the group-by-scenario interaction. P < 0.017 was the significance criterion when there were 3 groups being compared
