Pretreatment red blood cell distribution width as a predictive marker for postoperative complications after laparoscopic pancreatoduodenectomy

Figure 1 Relationship between pretreatment red blood cell distribution width and nutritional and inflammatory status. A-D: Negative correlation between pretreatment red cell distribution width and albumin (r² = -0.440, P < 0.001) (A) and prognostic nutritional index (r² = -0.442, P < 0.001) (B); and positive correlation between pretreatment red cell distribution width and neutrophil-to-lymphocyte ratio (r² = 0.258, P < 0.001) (C) and platelet-to-lymphocyte ratio (r² = 0.359, P < 0.001) (D) in peripheral blood in patients who underwent laparoscopic pancreatoduodenectomy. RDW: Red cell distribution width; PNI: Prognostic nutritional index.
