almost reached significancep = 0.062
On univariable logistic regression analysis, small postoperative graft diameter (OR: 0.141; 95% CI 0.021–0.970) and caudal anastomosis diameter measured on CT (OR: 0.226; 95% CI 0.059–0.859) were clear predictors of graft occlusion ( p = 0.047 and p = 0.029, respectively), while cranial anastomosis diameter almost reached significance ( p = 0.062) (OR: 0.179; 95% CI 0.029–1.092; Table 2 ).
