Analysis workflow. 791 IA genes were studied in three analyses: weighted gene co-expression network analysis (WGCNA) and functional annotation were performed on the GSE13041 data set (blue box); 108 survival associated IA genes were found by 3 different methods (Step-Cox, Quartile, Z-score) on de Tayrac dataset (middle green box); survival IA gene risk model was built on de Tayrac dataset and validated on 5 datasets: GSE 13041, TCGA, GSE2727, a local Agilent dataset, a local RT-Q- PCR dataset (right hand-side green box).
