  • Notes: Symbols > (greater than) and < (less than) indicate statistically significant differences (p≤0.05). Symbol ≈ indicates a difference that is not statistically significant (p>0.05).

  • NA=data not available for RVUs or comparison of high and low achievers by discipline with externship

  • NP=because the DBC fixed prosthodontics data had such high variability, the mean minus one SD was less than zero, so only students with zero fixed prosthodontics RVUs were considered low achievers; thus, statistical comparisons were not possible because there was no variability for this low achiever group (they were all zero RVUs).
