Construction and validation of the nomogram
SQUAMOUS CELL CARCINOMA, MONO
Due to our study only focusing on preoperative blood parameters, all variables in Table Selected factors in the training cohort for building the nomogram via univariate and multivariate analyses.Abbreviations: ALB, albumin; CEA, carcinoembryonic antigen; Hb, hemoglobin; LDH, lactate dehydrogenase; Lymph, lymphocytes; Mono, monocytes; Neut, neutrophils; NLR, neutrophil‐lymphocyte ratio; NSE, neuron‐specific enlase; PLR, platelet‐lymphocyte ratio; PLT, platelets; RBC, red blood cells; SCC, squamous cell carcinoma; SII, systemic immune‐inflammation index; WBC, white blood cells.indicates thevariables with significant differences were marked.The nomogram is presented in Figure Nomogram based on univariate and multivariate analyses.Calibration curve of the training (left) and validation cohorts(right).Decision curve analysis indicates better efficiency of our model than the other single indicators at thresholds between 0.1 and 0.2 (cyfra21‐1 left, ALB middle, CEA right).
