Table 3. Total outward forces acting on the frame at the AA and STJ levels for different bandwidths in the migration and no migration groups and relative P values.

Bandwidths	Migration group	No migration group	P value
Outward forces at AA level (N)
Bandwidth, 3 mm	18.1 (14.5–19.0)	15.9 (11.8–20.1)	0.40
Bandwidth, 5 mm	25.4 (20.5–28.0)	20.4 (15.3–26.1)	0.20
Bandwidth, 10 mm	32.6 (24.7–34.1)	27.8 (20.5–30.2)	0.40
Outward forces at the STJ level (N)
Bandwidth, 3 mm	0.0 (0.0–0.0)	0.9 (0.2–3.6)	0.002
Bandwidth, 5 mm	0.02 (0.0–0.8)	1.7 (0.7–7.3)	0.005
Bandwidth, 10 mm	3.2 (1.9–4.4)	11.7 (5.7–20.0)	0.002

The data are presented as median (interquartile range). AA, aortic annular; STJ, sinotubular junction.
