Figure 1From: Epigenetic markers for early detection of nasopharyngeal carcinoma in a high risk populationBox plot of seroreactivity of IgA/[EBNA-1+VCA-p18] ELISA by group (normal, high risk and NPC) with cut-off value of 0.354. The seroreactivity in NPC and high risk group was significantly higher than that in normal subjects (Mann-Whitney U test all p < 0.001). NPC = nasopharyngeal carcinoma, CoV = cut-off value.Back to article page
