*Number of years between the end of the second year and the start of the third year of the medical school curriculum

**Only 1 vs 3 pairwise comparison significant (p < .05)

^†Kruskal–Wallis and Multiple Linear Regression used to calculate the unadjusted and adjusted p values, respectively.

^‡All pairwise comparison (i.e., 0 vs 1, 1 vs ≥3, 0 vs ≥3) were significant (p < .05)

^§Only 1 vs ≥3 and 0 vs ≥3 pairwise comparisons were significant (p < .05)
