Correlations of expression data between microarrays and RT-PCR. a Spearman’s correlation plots show a positive correlation between data obtained by microarrays and RT-PCR. b The expression obtained by RT-PCR is consistent with microarrays data for all 7 evaluated genes. CMTM8, ID1, ID3 and IGJ shows an increased expression in bad prognosis group, whereas CENTG2, RGS1 and RPS4Y1 have low expression in this prognostic group in both techniques
