Figure 4. Clinical evaluation of patients with PTC in different risk groups. Clinical by the estrogen-related genes. Correlation analysis of risk score comprised of ERGs with age (A), gender (B), pathologic stage (C), T-stage (D), N-stage (E), M-stage (F), and neoplasm depth (G) in PTC patients. The risk score was significantly correlated with pathologic stage (p = 0.0017), T-stage (p = 0.0011), N-stage (p = 0.0018), and neoplasm depth (p < 0.01 and p = 0.41).
