From: Expandable external support device to improve Saphenous Vein Graft Patency after CABG

  Experimental (supported) grafts Control grafts
Inflammation (>1) 0/10 (0%) 0/10 (0%)

  5. Inflammation (0–3)
  6. 0 = no inflammation.
  7. 1 = a very mild infiltration of few inflammatory cells (neutrophils/lymphocytes).
  8. 2 = moderate infiltration of > 10 inflammatory cells (neutrophils/lymphocytes).
