TABLE 4.

Linear regression analysis: comparison of measurements of WSS per ATAA segment and tissue-derived parameters of corresponding segment from patient-specific excised tissue. circ = circumferential, long = longitudinal, SMC = smooth muscle cell. All results are statistically significant (p-value < 0.05).
