Fig. 1From: Prognostic significance of the combination of preoperative red cell distribution width and platelet distribution width in patients with gastric cancera Platelet distribution width (PDW) and serum CEA level were not significantly correlated (r = 0.025, P = 0.6); however (b), PDW and peripheral platelet count (PC) were significantly but weakly correlated (r = − 0.22, P < 0.0001)Back to article page
