2. Fig 1
Five-year patency of three subgroups of conduits. Fisher’s exact test: in situ versus free arterial, p = 0.02; in situ versus saphenous vein graph (SVG), p < ; and free arterial versus SVG, p = 0.08.

3. Fig 2
Actuarial graft patency on protocol-directed angiography at 1 month to 10 years. Log-rank test: in situ arterial (red line) versus free arterial (blue line), p = 0.14; in situ versus saphenous vein (green line), p = ; and free arterial versus saphenous vein, p = 0.07.

4. Fig 3
Comparative patencies of different in situ and free arterial conduits at 5 years. Fisher’s exact test: left internal thoracic artery (LITA) versus right internal thoracic artery (RITA), p = 0.7; and radial artery (RA) versus free right ITA (FRITA), p = 0.5. (SV = saphenous vein.)

Influence of target runoff on graft patency. Fisher’s exact test: saphenous vein (SV), p = 0.31; and radial artery (RA), p = 0.01.
