Figure 6.(A) Univariate Cox regression for risk-score, gender, age, and tumor stage in the training set found that risk score and stage were independent prognostic factors (p<0.05). (B) Multivariate Cox regression for risk-score, gender, age, and tumor stage in the training set found that risk score and stage were independent prognostic factors (p<0.05). (C) Univariate Cox regression for risk-score, gender, age, and tumor stage in the validation set found that risk-score and stage were independent prognostic factors (p<0.05). (D) Multivariate Cox regression for risk-score, gender, age, and tumor stage in the validation set found that risk score, age, and stage were independent prognostic factors (p<0.05). (E) Univariate Cox regression for risk-score, gender, age, and tumor stage in the entire set found that risk-score, age, and stage were independent prognostic factors (p <0.05). (F) Multivariate Cox regression for risk-score, gender, age, and tumor stage in the entire set found that risk score, age, and stage were independent prognostic factors (p <0.05).
