Figure 3. Analysis of clinical and immunological characteristics of C1 and C2 subtypes. (A) The distribution of clinical characteristics of C1 and C2 subtypes. (B) Sankey Diagram showing the distribution of immune subtypes in C1 and C2. (C) The differences of immune subtypes distribution between C1 and C2. (D) Survival curve analysis of immune subtypes. The asterisks represent the P-value (*p < 0.05). The statistical analyses were performed by the one-way ANOVA.
