Relationship between the HDL-C concentration and the clinical characteristics in 228 patients with NSCLC.

Mean ± SD stands for Mean ± standard deviation; HDL-C, high-density lipoprotein cholesterol; CRP, C-reactive protein; EGFR, Epidermal growth factor receptor; SCC, squamous cell carcinoma.
*P values were calculated by the unpaired Student’s t-tests or one-way ANOVA, P<0.05 considered as statistically significant.
**P values were calculated by the chi-square test (χ2 test), P<0.05 considered as statistically significant.
†Low serum HDL-C was defined as <40 mg/dL in men or <50 mg/dL in women, the data above those values were classified as the normal HDL-C.
††BMI, body mass index, weight divided by height squared kg/m2.
||The level of serum TG at 150 mg/dL or greater was defined as hypertriglyceridemia.
§Tobacco index indicated cigarettes per day multiplied years of smoking.
#The EGFR mutation status was unknown in 72 patients of the whole cohort.
‡TNM denoted tumor-node-metastasis.
