Figure 4From: Local critical stress correlates better than global maximum stress with plaque morphological features linked to atherosclerotic plaque vulnerability: an in vivo multi-patient studyCritical stress values correlated with cap thickness at critical site negatively (Pearson correlation coefficient r = 0.3953) and normalized lipid index positively(r = 0.3879). No correlation between critical stresses and the normalized wall index was found (r = 0.0444).Back to article page
