Figure 1From: Reference gene selection for head and neck squamous cell carcinoma gene expression studiesmRNA expression of 12 reference genes in HNSCC tissue and matched normal mucosa. Raw Cp values are represented for each gene by a box-plot. The central box represents the interquartile interval, the red line inside the box is the median value, and the extreme values represent the minimum and maximum values.
