Non-inferiority analysis. Error bars indicate two-sided 95% CI of the difference in the OSCE score between the CYPT and FLT groups. The broken line delineating the difference in the score (= 3.0) shows the non-inferiority margin; the region to the right of the margin indicates the zone of inferiority. The lower limit of the CI lies to the right of the non-inferiority margin, demonstrating non-inferiority of CYPT relative to FLT
