Methylation of the SST, TAC1, HCRT, NPY, and GAL gene promoters in 230 HNSCC samples. a Bar graph showing the methylation frequencies of the five genes. b Bar graph comparing the number of HNSCC cases to the number of methylated genes. c Double bar graph showing the methylation indices (MIs) according to the selected clinical parameters. The mean MI for each parameter was determined by using Student’s t test. Mean and standard deviation are also indicated, and statistical comparisons between groups are depicted. A probability of < 0.05 (*P < 0.05) was considered to represent a statistically significant difference
