The key gene list of LASSO and RF analysis.

Analysis	Genes
LASSO	RBM3, AGTR1, PSPH, PAK6, MTMR9, KANK4, CALN1, TCERG1L
RF	AGTR1, CNTN6, PCSK1, KIAA1191, RBM3, RIT2, UNC13C, RIIAD1, KCNJ6, SLC35D3, CHPF2, NUPR1, SGSH, MAN1C1, RBM17, DCC, DNM1L, TPBG, CCDC117, LOC101928307, DLL1, HSPA6, UBE2N, ABCA5, ROBO2, KLHL1, SEMA3G, SRA1, PLCXD2, DLK1

Abbreviations: LASSO, least absolute shrinkage and selection operator analysis; RF, random forest analysis. These genes in LASSO analysis are equally important. These genes in RF analysis are sorted by the parameter of increase in node purity. The two genes highlighted in bold are the overlap of the results of RF and Lasso analysis.
