FIGURE 5.
Risk score investigation of the differentially expressed long noncoding RNA (lncRNA) signature in gastric cancer. A risk score is shown according to the survival status and disease duration of the GC patients. (A) The abscissa refers to sample number and the ordinate depicts the risk score value. (B) GC patients were categorized into low-risk and high-risk groups based on the median inflection point of the risk score curve, which is represented by the dotted line. (C) lncRNA expression of low- and high-risk score patients. Colors from green to red indicate low to high lncRNA expression. (D) Overall survival (OS) status according to Kaplan–Meier analysis of the risk score. (E, F) Expression of the selected lncRNAs in (E) tumor vs. control samples, and (F) high-vs. low-risk patients. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. NS, non-significant.
