The CD4 concentration from local primary nasopharyngeal cancer specimen has no association with both EBNA1 oncoprotein (ρ Spearman correlation coefficient of 0.01; p value = 0.964) and LMP1 oncoprotein (ρ Spearman correlation coefficient of 0.29; p value = 0.177) from local primary nasopharyngeal cancer specimen, Fig. 4. The gene discussed is CD4; the disease is nasopharyngeal carcinoma.
