From: Reference gene selection for head and neck squamous cell carcinoma gene expression studies
Expression ratio between HNSCC tissue and normal mucosa in the 12 reference genes. For estimation of the individual expression of each gene, the expression ratios of paired tissue specimens were calculated (R = HNSCC/normal). The log distribution of these ratios is represented for each gene by a box-plot. The central box represents the interquartile interval, the white line inside the box is the median value, and the extreme values represent the minimum and the maximum.
