Fig. 3From: Screening and identification of immune-related genes for immunotherapy and prognostic assessment in colorectal cancer patientsValidation of IRGs associated with survival. A Expression level of NRG1 is positively correlated with overall survival. B Expression level of PGR is negatively correlated with survival time. The horizontal axis is survival time, the vertical axis is overall survival, red represents the high gene expression group, black represents the low gene expression groupBack to article page
