TABLE 4.

Threshold analysis for the relationship between onset-to-TEVAR time and follow-up death risk.

Models	Adjusted HR (95% CI) P-value
Model I
One line slope	1.0 (1.0, 1.0) 0.288
Model II
Turning point (K)	9.4
<K slope 1	7.8 (0.5, 120.5) 0.142
>K slope 2	1.0 (1.0, 1.0) 0.685
LRT test	0.002*

Values are presented as the HR (95% CI) P-value. Adjusted for: age, BMI, hypertension, CAD, diabetes, stent brand, chimney TEVAR; LRT test: logarithmic likelihood ratio test.

*Indicates that Model II is significantly different from Model I.
