The 95% confidence interval (CI) is within the light blue shaded region. These models allow a program director to estimate a resident’s risk (PGY 3) of RCPSC examination failure based on their year of training and ACR score. For example, a resident scoring in the 25th percentile has an 18% chance of failure (a) with a 95% confidence interval (CI) lower limit of 8% (b) and a 95% CI upper limit of 32% (c).
