Clinical significance of serum levels of vascular endothelial growth factor and its receptor in biliary disease and carcinoma

Figure 2 VEGF (A), VEGF/PLT (B), and VEGFR1 (C) levels in patients with biliary disease and healthy volunteers. The mean value of each group is presented as a bold line. VEGF/PLT: the calculated parameter by dividing the serum VEGF values (pg/mL) by the platelet counts (×10⁶/mL); Cholangitis: patients with acute cholangitis or cholecystitis; Cancer: patients with biliary neoplasms; PBC/PSC: patients with primary biliary cirrhosis or primary sclerosing cholangitis; normal: healthy volunteers.
