Validation data sets confirm the reliability of the analysis in Fig. 3. (A) LUAD samples were categorized into LRG as well as HRG based on the optimal RS threshold. Blue is the LRG, while red is the HRG. (B) Correlation between RS and survival status. Blue represents alive individuals, and red represents deceased patients. (C) Overall probability of survival in the low risk as well as high risk LUAD groups. Blue is the LRG, while red is the HRG. (D) 1-, 3-, and 5 survival rates (SRs) in LUAD patients. Red is 1-year, green denotes 3-year, as well as blue signifies 5-year SRs. (E) Expression of GAB3 and IL16 in LUAD samples from HRG as well as LRG. Values closer to −1 mean lower expression, while those closer to 1 signify higher one.
