Evaluation of multi-module lncRNA signature. A A forest plot showing the HR and p-value under multivariable Cox PH model to assess overall survival of LUAD patients with high v.s. low expression of the four lncRNA modules (N1, N2, N4, P3) and the 4-module signature. Age and TNM stage were adjusted. B Kaplan–Meier curve of the OS in the 4-module Signature. Log-rank test was used. C Kaplan–Meier curve of the EFS in the 4-module Signature. Log-rank test was used. D The comparison of AUC of module N1, N2, N4, P3 and the 4-module signature in five different time points
