Figure 6. Construction of a nomogram for overall survival prediction in ESCC. (A) The nomogram consists of age, grade, stage and the risk score based on the eight-lncRNA signature. (B) Calibration curves of the nomogram for the estimation of survival rates at 1-, 3-, 5- year. (C) The Kaplan-Meier curves of the risk subgroups stratified by the tertiles of total points derived from the nomogram.
