From: Graduate medical education-led continuous assessment of burnout and learning environments to improve residents’ wellbeing

  December 2017; n = 130 May 2018; n = 131 December 2018; n = 126 May 2019; n = 133 December 2019; n = 121 Kruskal–Wallis p value MANOVA
p value

  1. Legend:
  2. () = standard error of the mean
  3. N = total number residents who completed the survey for each time period
  4. Results of Kruskal–Wallis test for trends:
  5. ! Based on the five tests performed, a Bonferroni-corrected alpha level of p = 0. 0125 (0.05/4) was reported per test as significant for the Kruskal–Wallis test. Thus, the p value of 0.04 was not significant in the Kruskal–Wallis test for trends
  6. Results of MANOVA analysis:
  7. *There was homogeneity of variance-covariances matrices, as assessed by Box’s test of equality of covariance matrices (p = 0.705). Wilks’ Lambda multivariate statistics p value was 0.205 which showed that there were no significant differences between the groups. On tests of between-subjects effects Emotional Exhaustion Score had p value of 0.03 which became non-significant p = 0.055 on post-hoc Bonferroni correction
