Figure 5. Kaplan-Meier survival curves for patients on the anti–CTLA-4 study (top, in blue) or the anti–PD-1 study (bottom, green).

In the left column, patients are separated by clonality status (<0.1, diverse; >0.1, clonal). In the right column, patients are separated by high (>100) or low (<100) number of expanded clones. A likelihood ratio test was used to assess significance.
