There was also the discrepancy between the two groups in VEGF expression level (proximal, 126.35 vs. 98.87; middle, 125.23 vs. 102.70; and distal, 130.18 vs. 98.42), and mean value of VEGF expression was 127.25 ± 2.60 in diabetes and 100 ± 2.35 in normal control. Here, VEGFA is linked to diabetes mellitus.
