Changes in diameter for the entire cohort and for acute and chronic dissections, according to false lumen status. Arrows indicate changes in aortic diameter (↑ = increase in diameter, ←→ = no changes in diameter and ↓ = decrease in diameter). Colours indicate the effect of diametric changes in relation to remodelling (green: favours positive remodelling, yellow: no effect on remodelling and red: favours negative remodelling).
