Identification of key ribosomal proteins. (A) The lambda.min value of lasso coefficient was used as cut-off. (B) The potential prognostic proteins were determined by lasso variable trajectory diagram. (C) Key ribosomal proteins were identified by univariate cox regression analysis with p value < 0.1. RPL4, RPS19, RPS16, RPLP0, RPS2, RPS26 and RPS25 had close relation to overall survival of LUAD patients. (D) The relative expression of the 7 key ribosomal proteins. (E) The relationship between risk score and survival time, expression levels of 7 key ribosomal proteins. (F) The survival curve of risk score.
