In pairwise comparisons , the risk of the primary outcome was significantly higher in the femoral group than in the subclavian group ( hazard ratio , @ ; @ % confidence interval -LSB- CI -RSB- , @ to @ ; P = @ ) and in the jugular group than in the subclavian group ( hazard ratio , @ ; @ % CI , @ to @ ; P = @ ) , whereas the risk in the femoral group was similar to that in the jugular group ( hazard ratio , @ ; @ % CI , @ to @ ; P = @ ) .
