Supplementary Figure S1. Distribution of correct responses to SC or MS questions #1-30. Mean values plus standard error of the mean are plotted in the ordinates. Variance analysis (ANOVA) revealed significant differences between all groups compared here (P < 0.001). By pairwise comparison (Bonferroni post-tests), differences between individual pairs of questions were analyzed and labeled in the graphs (*P < 0.05). (A) group A-SC compared to B-MS. This graph compares the correct answers for objectives #1-15 using both question formats. (B) group A-MS compared to B-SC. This graph compares the correct answers for objectives #16-30 using both question formats. (C) group A-SC compared to B-SC. (D) group A-MS compared to B-MS. The graphs in (C) and (D) compare the correct answers for the same question format but using different questions (e.g., #1 versus #16)
