The ROC curves of the CRP, ANC, ALC, NLR, and CLR as the inflammatory markers were compared for the predictive power of in‐hospital mortality. Abbreviations: CLR_post, the ratio of C‐reactive protein to lymphocyte count value in the postoperative period; CLR_pre, the ratio of C‐reactive protein to lymphocyte count value in the preoperative period; NLR postop, the ratio of neutrophil count to lymphocyte count value in the postoperative period; NLR preop, the ratio of neutrophil count to lymphocyte count value in the preoperative period; postop ALC, absolute lymphocyte count value in the postoperative period; postop ANC, absolute neutrophil count value in the postoperative period; postopCRP, C‐reactive protein value in the postoperative period; preop ALC, absolute lymphocyte count value in the preoperative period; preop ANC, absolute neutrophil count value in the preoperative period; preopCRP, C‐reactive protein value in the preoperative period
