Correlation of CRP concentration with lipid levels and smoking profile in 228 NSCLC patients.

CRP, C-reactive protein; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; TC, total cholesterol; TG, triglyceride; EGFR, Epidermal growth factor receptor.
*P values were calculated by the Mann-Whitney U Test, P-value <0.05 considered as statistically significant.
**P values were calculated by the chi-square test (χ2 test), P-value <0.05 considered as statistically significant.
†High serum CRP was defined as >3.0 mg/L, the data below the cut off value were classified as the normal CRP.
††The cut-off value of HDL-C was 40 mg/dL in men or 50 mg/dL in women.
||Tobacco index indicated cigarettes per day multiplied years of smoking.
§The EGFR mutation status was unknown in 72 patients of the whole cohort.
