Two-way sensitivity analysis on CRT risk for radiation-related cardiac and second cancer mortality by various levels of short-term CT EFS. These figures show 2-way sensitivity analysis on CRT relative risk for radiation-related cardiac and second cancer mortality for the following levels of short-term CT EFS: probability = 0.82 (A), 0.87 (base case; B), and 0.90 (C). In each panel, the region where CT is preferred is indicated by the light green shaded area, and for CRT, the dark gray shaded area.
