KM analysis, pathway map and PPI network analysis for gene screening. KM plots for ATG2B (A), ATG10 (B) and DAPK1 (C) in training set: x-axis referred to living time (months), y-axis referred to the survival probability (up) and  the group (down), number table in the lower part of the plot referred to number of patients at risk. (D) Autophagy pathway map (hsa04140) from KEGG website: red nodes referred to ATG2B, ATG10 and DAPK1, blue nodes were the other mapped ARGs screened by LASSO. (E) PPI network for proteins encoded by LASSO screened ARGs (interaction score ≥ 0.4): the width of the line referred to the co-expression strength between the two nodes
