a–d Critical attitudes towards guidelines by physicians’ specialisation and type of barrier amongst DGP members. Y-axis represents values from 0 (do not agree) to 3 (agree) for the summarised questions by topic. Boxplots (median, 25 and 75% percentiles; whiskers: 1.5 interquartile range) are shown together with a frequency distribution. Asterisks show significant (p < 0.05) pairwise comparisons for those outcomes with significant overall tests (p < 0.05)
