Adventitial microvessel (neo-vasa vasorum) count in vein grafts from diabetic and non-diabetic pigs treated orally with folic acid once daily for 1 month prior to explantation. Data are expressed as median and interquartile range, n=6. Statistical significance was determined using a Mann–Whitney test with Bonferroni adjustment and the tau-b test. ***p<0.001 (ungrafted vein vs vein graft at 1 month); *p<0.05 (control vs diabetic vein graft at 1 month); †p< 0.05 (diabetic vein graft vs diabetic vein graft+folic acid at 1 month)
