Univariate and multivariate regression of ascending aorta flow displacement and curvature versus diameter and length growth of the ascending aorta.
| S1 diameter growth / year (mm/y) |
S1 length growth / year (mm/y) |

| Ascending aorta curvature radius | −0.018 [0.006] | 0.01 | −0.037 [0.018] | 0.04 |
| Multivariate* | ||||
| Flow displacement | −0.3 [1.4] | 0.85 | 9.1 [3.3] | 0.01 |
| Ascending aorta curvature radius | −0.017 [0.007] | 0.01 | −0.026 [0.020] | 0.21 |
* Diameter growth adjusted for age, sex, baseline diameter and heart rate; length growth adjusted for age, sex, baseline length and history of hypertension and diabetes.
