Results from linear (generalized) mixed modelling investigating the association between rater and case characteristics with confidence in assessment, general retreatment recommendation (any retreatment), and specific retreatment recommendations (coiling, stent and coiling, clipping, other endovascular treatment)

↵a Rated from completely uncertain (1) to completely certain (6).
↵b Binary compared with no treatment; odds ratios of >1 indicate a higher probability of treatment, and odds ratios of <1 indicate a lower probability of treatment with an increase in the predictors.
↵c In SD units.
↵d P < .050.
