Multiple regression analysis with regard of diabetes without foot ulcerations (Non DFS) compared to healthy control subjects showed a significant negative association between Non DFS and serum levels of omentin (B =− 0.31 p < 0.003) and a positive association between Non DFS and LH/HF (B = 1.50; p = 0.03) (see Table 3). Here, ITLN1 is linked to diabetes mellitus.
