A, Highly experienced group; B, experienced group; C, little‐experienced group.
The participants answered questionnaires including a self‐assessment of confidence levels for 21 surgical skills (0 points, cannot do at all; 5 points, can do with help of an adviser; 10 points, can do independently). P‐values < 0.0167 (= 0.05/3 with a Bonferroni correction for multiple comparisons) were considered to be statistically significant.
*P < 0.0167 (=0.05/3); **P < 0.001; ***P < 0.0001. ns, >0.0167.
