Protective biomechanical and histological changes in the false lumen wall in chronic type B aortic dissection.
Article in JTCVS open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: The outer false lumen wall (FLW) changes from thin/compliant to thick/rigid as aortic dissection transitions from the acute to chronic phase. This study investigates biomechanical stiffness and histological changes of the FLW as the dissected aorta ages. Methods: The free outer FLW from human tissue was analyzed from chronic type B dissection (chronic-FLW) n = 10, acute type A dissection (acute-FLW) n = 10, and transplant donor descending aorta that was manually peeled into 2 layers (control-FLW) n = 17. Biaxial tension testing in the longitudinal and circumferential directions was performed and stress-strain curves were obtained. A lower and higher tangent modulus was determined to assess stiffness. Quantification of collagen and elastin was performed by calculating the fibers' volume fraction from Z-stack scans. Results: The higher tangent modulus of chronic-FLW is larger ( Conclusions: As the acutely dissected aorta transitions to the chronic phase, the FL remodels by increasing collagen, decreasing elastin, and increasing aortic stiffness and thickness. This change in the chronic-FLW may be a protective adaptation to prevent FL enlargement and rupture in type B aortic dissection.
