Supplementary Figure 2. Scaled Schoenfeld residuals for corresponding fixed-effect models, inclusive of study as a categorical variable, relating to mixed-effects survival models in Table 2. A. Model I compares BRAF classes across all patients irrespective of additional Ras mutation; B. Model II compares Class 1 without Ras vs Class 3 with Ras mutations; C. Model III examines additional Ras mutation status within Class 3. P-values represent significance of violation of proportional hazards assumptions.
