Association between morphological feature change over time and time-to-occurrence of a LAE corrected for the baseline values of all other features significant in the univariable analysis, and corrected for the presence of connective tissue disease. HR: hazard ratio; CI: confidence interval; Max: maximum; mm: millimeter; TL: true lumen; FL: false lumen; FLT: false lumen thrombosis; ICA: intercostal arteries; NA: not applicable (not significant in univariable analysis).
