Comparison between the seemingly gold-standard approach and other approaches. Between any two approaches, similarity in the estimated peak wall tension index is quantified by the slope; consistency in the dissimilarity, if any, is quantified by the Pearson’s coefficient; and the similarity in the ranking of the aneurysms based on peak wall tension index is quantified by the Spearman’s coefficient.
