Table 4 C-statistics of the different models for predicting cardiovascular mortality

Models	C-statistics (95% CI)	△C-statistics (95% CI)	p value
Original model	0.728 (0.681–0.775)	–	–
Original model + leukocytes	0.744 (0.697–0.791)	0.016 (0.003–0.037)	0.069
Original model + neutrophils	0.753 (0.707–0.800)	0.025 (0.024–0.046)	0.022
Original model + lymphocytes	0.740 (0.693–0.787)	0.012 (− 0.003 to 0.026)	0.106
Original model + monocytes	0.729 (0.682–0.776)	0.001 (− 0.004 to 0.006)	0.846
Original model + eosinophils	0.738 (0.689–0.789)	0.010 (− 0.005 to 0.024)	0.169
Original model + basophils	0.738 (0.690–0.787)	0.010(− 0.008 to 0.028)	0.271

Original model + NLR	0.765 (0.720–0.809)	0.037 (0.021–0.068)	0.002
Original model + MLR	0.751 (0.708–0.794)	0.023 (0.012–0.043)	0.004
Original model + ELR	0.739 (0.690–0.789)	0.011 (− 0.007 to 0.027)	0.217

Original model included age, male gender, BMI, family history of CAD, smoking, hypertension, DM, HDL-C, non-HDL-C, hsCRP, creatinine, LVEF, troponin I, use of statin, ACE-I/ARB, PCI
△C-statistics indicated the difference in C-statistic between original model and models additionally including leukocytes, neutrophils, lymphocytes, monocytes, eosinophils, basophils, NMLR, NLR, MLR, or ELR
BMI body mass index, CAD coronary artery disease, DM diabetes mellitus, HDL-C high-density lipoprotein cholesterol, PCI percutaneous coronary intervention, hsCRP high sensitivity C-reactive protein, NMLR neutrophil-plus-monocyte-to-lymphocyte ratio, NLR neutrophil-to-lymphocyte ratio, MLR monocyte-to-lymphocyte ratio, ELR eosinophil-to-leukocyte ratio
