Figs. 4-A and 4-B Phase-3 knowledge assessment performance by participant group. Fig. 4-A The mean overall scores. The mean pre-course and post-course assessment scores (percentage of total questions answered correctly) were calculated for the cohort as a whole, by job title or years of experience (OCOs with <10 years of experience, OCOs with ≥10 years of experience, OCOs with a BSc degree, orthopaedic surgeons, and others) and by pre-course performance quintile. Fig. 4-B The mean change in performance. The change in number of questions answered correctly between the pre-course and post-course assessments was calculated for each participant. The mean change in performance was calculated by participant group. The asterisk denotes a significant change (p < 0.05) in mean scores between the pre-course and post-course assessments, calculated using paired t tests.
