Figure 1 Immunohistochemical expression of combined intensity and distribution (H-score) for endothelin 1 (ET-1), ETA, and ETB in varicose (V) versus control (c) veins. (Whiskers: minimum to maximum; P<.0001, Wilcoxon signed rank test.)

Supplemental Figure 1 (A) Control vein stained poorly for endothelin 1 (ET-1). (B) Increased immunostaining for ET-1 in varicose vein. Note intima and media tunica thickening. ETA immunostaining in control vein (C) and in varicose vein (D). Analogous low ETB expression in control vein (E) compared with varicose veins (F). All microphotographs, ×20.
