Association of elevated CSF1R, CSF1, and IL34 expression with survival in primary CRCs. Kaplan-Meier analyses of survival with data from the (A) TCGA database, the (B) GSE39582, and the (C) GSE37892 cohorts using log-rank tests. Below the graphs, the numbers of patients with high or low expression of the indicated mRNA at the respective time point is provided. CI, confidence interval; HR, hazard ratio; mOS, median overall survival.
