Figure 9. Constructing a prediction nomogram. (A, B) Univariate and multivariate regression analysis showed that CBX3, CBX8, age, gender, pT stage, pN stage, and pM stage were independent factors for the prognosis of gastric cancer patients; (C, D). The predictive nomogram suggested that overall survival rates over 1, 2 and 3 years could be reasonably predicted. A dashed diagonal line represents the ideal nomogram. Abbreviation: CBXs, chromobox proteins.
