Lumen diameter
There was no interaction between the pressure test and harvest technique for lumen diameter assessed using IVUS (p=0.49). Consistent with this, comparing the harvest techniques, the average lumen diameter was similar in the two groups (geometric mean ratio, GMR (pedicled:conventional) = 1.01, 95%CI 0.95, 1.07, p=0.81). It was also similar in the two pressure test groups (GMR (low:high) = 0.97, 95%CI 0.91, 1.02, p=0.24,Figure 2, Table 4, Appendix Table A6 ).
