“…Weighted gene co-expression network analysis (WGCNA) and least absolute shrinkage and selection operator (LASSO) Cox regression analysis are crucial bioinformatics methods at present [ [13] , [14] , [15] ]. These analyses may help researchers identify and study modules and reveal the key genes involved in different diseases [ [16] , [17] , [18] ]. Therefore, we established a POLE -related risk score (PRS) model employing WGCNA and LASSO Cox regression analysis and assessed its capacity to anticipate the EC prognosis and to identify differences in response to immuno and chemotherapy between risk groups.…”
