Association between central venous pressure and postoperative pulmonary complications in living-donor liver transplantation for pediatric patients

Figure 3 Nonlinear relationship between central venous pressure and postoperative pulmonary complications. Adjustment factors included age + sex + cold ischemia time + blood loss + urine + liquid transfusion + blood transfusion + ischemia-reperfusion + anthepatic phase time + pediatric end-stage liver disease sore. Restricted cubic splines results for the incidence of postoperative pulmonary complications. Curves represent estimated adjusted odds ratios (ORs), and shaded ribbons represent 95% confidence intervals. The vertical dotted line represents the lowest point of the curve which represents the lowest OR. The horizontal dashed line represents a hazard ratio of 1.0. PPC: Postoperative pulmonary complication; CVP: Central venous pressure.
