Stent fracture after transjugular intrahepatic portosystemic shunt placement using the bare metal stent/stent-graft combination technique

Table 3 Multivariable logistic regression of the risk factors for stent fracture

Characteristic	Adjusted odds ratioa	P value	95%CI
Stent number	22.2	0.038	1.2-415.4
Reoperation
No	Reference
Yes	0.3	0.562	0.0-13.8
Stent Angle
Angle 1	0.9	0.191	0.8-1.3
Angle 2b	1.1	0.020	1.0-1.3

^aModels were adjusted for covariates with clinical relevance (i.e., stent number, reoperation and Angle 1) and those found to be significant in univariate analyses (i.e., Angle 2).

^bBending angle of the axis of the end segment and the mid-segment of the stent in the sagittal plane.

CI: Confidence interval.
