BSA = body surface area, BMI = body mass index, CTA = computed tomography angiography, Dmax = maximal aneurysm diameter, ILT = intraluminal thrombus. Values denote n (%), mean (standard deviation) or median (interquartile range). ^† Estimates refer to estimates from mixed effects models, where the variable is a function of time with random intercepts and slopes. Standard deviation refers to the variability in the random slopes.
