The changes in (a) simulation-based training in and (b) assessment of the generic non-technical skills within each professional group from 2011 to 2015. The ratios represent the relative frequencies (%) of 2015 divided by the relative frequencies (%) of 2011 across all four ordinal categories, with a ratio = 1 (dashed line) indicating no change in relative frequency and a ratio < 1 or > 1 respectively a decrease or an increase in frequency. Missing bars are due to categories with no data in one or both of the years surveyed, and thus, no computable ratio
