Figure 3. Validation of the model using four independent GEO database cohorts. In the GSE37745 cohort, (A) Kaplan-Meier curves depict the prognosis for the high- and low-risk groups, and (B) the AUC values at one-, three-, and five-year. In the GSE72094 cohort, (C) Kaplan-Meier curves show the prognosis of the high- and low-risk groups, and (D) the AUC values at one-, three-, and five-year. In the GSE50081 cohort, (E) K-M curves display the prognosis for the high- and low-risk groups, and (F) the AUC values at one-, three-, and five-year. In the GSE31210 cohort, (G) Kaplan-Meier curves depict the prognosis of the high- and low-risk groups, and (H) the AUC values at one-, three-, and five-year.
