Fig 1 Anatomic differences of intima (I) and media (M) according to leptin tertiles. Upper, Hematoxylin and eosin staining. Lower, Trichrome staining. Significant differences in intimal hyperplasia and medial thickening were observed across tertiles. Similarly, medial fibrosis was most severe in the highest tertile.

Fig 2 Cellular phenotype difference according to leptin tertiles. In the most specimens across the three tertiles of leptin, the majority of cells in the intima were α-smooth muscle actin (SMA)-positive, vimentin-positive, desmin-negative myofibroblasts. Particularly in the lowest tertile of leptin, desmin-positive smooth muscle cells were more frequently observed than in the two upper tertiles of leptin.

Fig 3 Leptin receptor (ObR) staining in intima (I) of cephalic vein. Immunohistochemical (IHC) staining of leptin receptor showed significant inverse relationship with serum leptin tertiles, indicating downregulation of leptin receptors in higher leptin tertiles.
