Development and internal validation of an immune-based prognostic modeling of early-onset colorectal cancer via machine learning

Figure 1 Kaplan-Meier analysis of progression-free survival by risk stratification and immunological status. A: Estimates of progression-free survival according to risk group; B: Progression-free survival stratified by tumor stage and CD16+CD56+ natural killer cell percentage. PFS: Progression-free survival; NK: Natural killer.

Figure 2 Time-dependent receiver operating characteristic curves for prediction of progression-free survival at 1 year, 3 years, and 5 years. ROC: Receiver operating characteristic; AUC: Area under the curve; CI: Confidence interval.
