Figure 1.

Mean percentage (95% confidence interval) values for the repeated multi-choice tests categorised by lecture type and topic. The differences between baseline, post- lecture and delayed testing are statistically significant (p = 0.037). The difference in baseline for the two topics is statistically significant (p < 0.001). The difference in delayed testing between attendees and absentees is significant (p < 0.001). Trad = traditional lecture; EVS = EVS lecture; Cx = cervical cancer topic; Br = breast cancer topic; Pre = test sat immediately before lecture; post = test sat immediately on completion of lectures; Del = delayed test 8–12 weeks after lecture; Absent = students who did not attend lectures but sat the delayed test.
