Figure: Case characteristics and retreatment recommendations
Note:—Acom indicates anterior communicating artery; Pcom, posterior communicating artery; A., arteria.
a Rated from complete occlusion, neck remnant, to residual aneurysm.
b Rated from better, same, to worse.
c Rated from completely uncertain (1) to completely certain (6).
d Rated from standard, difficult, to unbearable risk.
e Rated from coiling only, stent-assisted coiling, clipping, other, or no retreatment.

Results from linear (generalized) mixed modelling investigating the association between 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.

↵d Ruptured (1) versus asymptomatic (0).
↵e Elderly, older than 50 years, (1) versus younger, 50 years or younger (0).
↵f Proportion of ratings of residual versus complete/neck remnant aneurysm from 0 to 1.
↵g Proportion of ratings of worse-versus-the same/better condition from 0 to 1.
↵h Proportion of ratings of difficult/unbearably risky versus standard retreatment from 0 to 1.
