Identification of Combinations of Plasma lncRNAs and mRNAs as Potential Biomarkers for Precursor Lesions and Early Gastric Cancer

Figure 5

Receiver operating characteristic curve analysis of plasma RNAs discriminates patients with EGC from healthy participants. (a) Receiver operating characteristic curve analysis of single plasma RNA with PPBP, RGS18, CEBPA-AS1, INHBA-AS1, AK001058, and UCA1. (b) Combined receiver operating characteristic curve analysis of abovementioned plasma RNAs. (c) A nomogram predicting the risk of GC for patients with EGC. The value of each of variable was given a score on the point scale axis. A total score could be easily calculated by adding each single score, and by projecting the total score to the lower total point scale, we were able to estimate the probability of GC. CI, confidence interval; AUC, area under the curve; (C) CEBPA-AS1; (I) INHBA-AS1; (A) AK001058; (U) UCA1; (P) PPBP; (R) RGS18; EGC, early gastric cancer.
