Outcome #Grafts in No Touch
N = 191
#Grafts in Conventional
N = 243
No Touch vs Conventional
Odds Ratio (95% Confidence Interval)
p-value Interaction p-value
Total Occlusion 18 (9.4%) 36 (14.8%) 0.60 (0.32–1.12) 0.107 0.998
50–99% Stenosis or Total Occlusion 19 (9.9%) 46 (18.9%) 0.49 (0.27–0.88) 0.018 0.933
  1. Legend: Chi-square p values are from the generalized estimating equations model results. OR = odds ratio. CI = confidence interval. The interaction p value refers to the interaction between the numbers of grafts in each patient and treatment received. Endoscopic veins are excluded
