Early prediction of anastomotic leakage after rectal cancer surgery: Onodera prognostic nutritional index combined with inflammation-related biomarkers

Figure 1 Area under the curve of the Onodera prognostic nutritional index, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and combined prediction. OPNI: Onodera prognostic nutritional index; NLR: Neutrophil-to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio; AUC: Area under the curve.
