Figure 7. Correlation between the expression levels of individual IRGs from the ten-IRG prognostic signature and OS of CRC patients in the TCGA database. Kaplan-Meier survival plots show OS of CRC patients with high (red line) and low (blue line) expression of the ten individual IRGs. Kaplan-Meier survival curves for (A) A2ML1, (B) CALB2, (C) CD1B, (D) COL22A1, (E) FCRL2, (F) HAND1, (G) IDO1, (H) MAP2, (I) NKAIN4, (J) VAX2. Note: p<0.05 by the log-rank test.
