The correlation coefficients of BMI and gene expression in the group of subjects with laryngeal cancer are as follows: PD-1, r = 0.030 (p = 0.8582), PD-L1, r = −0.051 (p = 0.7564), and in the control group: PD-1, r = −0.264 (p = 0.1318), PFD-L1, r = −0.141 (p = 0.2331). This evidence concerns the gene CD274 and laryngeal carcinoma.
