All variables with p values < 0.2 in univariable analysis, i.e., ASA-classification, hemoglobin < 7.5 mmol/L, CRP > 10 mg/L, eGFR ≤ 45 mL/min/1.73 m2, and metastatic disease at presentation, were entered into the multivariable logistic regression analysis. This evidence concerns the gene CRP and metastatic neoplasm.
