The Kaplan–Meier estimate of overall survival in the 51 patients with metastatic colorectal cancer enrolled on the study. The dashed lines represent the 95% confidence interval (CI) about each successive estimate of the survival rate. The median survival was 21.2 months [95% CI, 13.8-not available months]. The 1-year survival rate was 75% (95% CI, 0.63–0.88). The 2-year survival rate was 48% (95% CI, 0.31–0.64)
