Figure 2. Prognostic methylation classifier can predict overall survival of EAC and ESCC. Waterfall plots show the risk scores of prognostic methylation classifier between high-risk and low risk patients for (A) EAC and (B) ESCC. The dash lines represent the median of the risk score. Kaplan-Meier curves were used of overall survival in high and low risk groups for (C) EAC and (D) ESCC. The cutoff values for the high and low risk groups were based on the median of the risk score.
