Pearson’s correlation coefficient (r) values for comparisons of varicosity counts between subregions of adjacent cross-sectional tissue samples within the aortic arch or thoracic aorta. Reliability between measurements is demonstrated by high correlations, supporting the reproducibility of the proposed method for image acquisition, data processing, and quantification.
