Construction and validation of prognostic nomogram
Nomogram‐predicted OS, x‐axis
We depict the model incorporating six independent factors that affect overall survival. (Figure Nomogram predicting 1‐, 3‐, and 5‐year OS for patients with ES.Receiver operating characteristic curve analysis for evaluating the accuracy of the 1‐, 3‐, and 5‐year nomogram. (A) training group and (B) validation group.Calibration plots of the nomogram for predicting 1‐, 3‐, and 5‐year OS. Nomogram‐predicted OS is plotted on the x‐axis; actual OS is plotted on the y‐axis.

(A) OS among ES patients based on M0 stage, M1 stage, and unknown M stage. (B) OS among ES patients based on G1‐G2, G3‐G4, and unknown grades. (C) OS among ES patients based onT1 T2 and unknown T stage. (D) OS among ES patients based on surgery and no surgery. (E) OS among ES patients based on superficial appendicular locations; deep appendicular locations; superficial axial locations; and deep axial locations.
