Fig. 3From: Epigenetic stratification of head and neck cancer survivors reveals differences in lycopene levels, alcohol consumption, and methylation of immune regulatory genesMethylation patterns are reflective of total serum lycopene and alcohol consumption. a Circulating carotenoids and b cytokines were measured in the three differentially methylated groups. Data are presented as mean ± SEM. *Denotes p value <0.05 using posthoc Tukey test. c Group differences in lifestyle parameters were assessed using chi-square tests. Y-axes represent the percentage of participants within each category, with the actual number of participants noted on the graph. *Denotes p value <0.05 using chi-square testBack to article page
