γ-Glutamyl hydrolase mRNA expression according to the CIMP status, tumour site, TILs and BRAF mutation status in an Australian CRC cohort was shown by boxplot. The level of GGH mRNA expression was significantly different between all dichotomised variables (Mann–Whitney U-test; CIMP, P=0.013; tumour site, P=0.021; TILs, P=0.001; BRAF mutation, P=0.002).
