Systematic Construction and Validation of a Novel Ferroptosis-Related Gene Model for Predicting Prognosis in Cervical Cancer

Figure 1

Identification of ferroptosis-associated subtypes using nonnegative matrix cluster analysis. (a) The optimal value was determined to be 2, and TCGA cervical cancer samples could be divided into two subgroups, C1 and C2. (b, c) K-M survival curves of overall survival (OS) and disease-free survival (PFS) in C1 and C2 subgroups. (d) Heat map of age, stage, grade, BMI, and ferroptosis-related gene expression across subgroups.
