  1. aThe relative CMTM4 expression level was calculated from the tumour (T) versus paired adjacent non-tumour tissue (N)
  2. bThe P-value was calculated using one-way ANOVA (for the classification variables, such as gender, stage and grade) or Pearson correlation analysis for two variables (for the continuous variables, such as age)
  3. cn.a. indicates not available due to a small sample size
  4. dThe tumour stage was defined according to TNM (International Union Against Cancer, 6th edition, 2002)
