External validation of the independency of the EMT-related RS model in predicting prognosis in GSE66229 and GSE84437 datasets. (a, b) Heatmap of the expression of SERPINE1, PCOLCE2, MATN3, and DKK1 in high- and low-RS groups in (a) GSE66229 and (b) GSE84437 datasets. Red and green indicate up- and downregulation.
