Figure 2. (A) Univariate Cox regression analysis for the prognostic significance of NDC1 for OS. HR>1 indicates NDC1 is a risk factor and HR<1 indicates NDC1 is a protective factor. P < 0.05 was considered statistically significant. (B) Kaplan-Meier survival analysis for OS. P < 0.05 was considered statistically significant (Red for high NDC1 expression and blue for low NDC1 expression). (C) Univariate Cox regression analysis for the prognostic significance of NDC1 for PFS. HR>1 indicates NDC1 is a risk factor and HR<1 indicates NDC1 is a protective factor. P < 0.05 was considered statistically significant. (D) Kaplan-Meier survival analysis for PFS. P < 0.05 was considered statistically significant (Red for high NDC1 expression and blue for low NDC1 expression).
