Differences between groups were highly significant (χ 2 = 80.94, degrees of freedom (df) = 7, P < 0.001).
More detailed analysis (Figure 2 ), shows a significant interaction of candidate and examiner ethnicity for communication skills and ethics ( p = 0.003), a marginally significant effect for the respiratory station ( p = 0.046), and a marginally non-significant effect for history-taking ( p = 0.078).
Overall, the station × ethnicity interaction was almost significant (F (6,11190) = 1.94, P = 0.071), but there was no suggestion of station × gender or station × ethnicity × gender interaction ( P = 0.908 and P = 0.540 respectively).
