Relative risks representing the ratio of 11C versus 12C NTCP values for individual liver patients for each of the six models considered in the study. Value of RR < 1 means that the 11C plan is beneficial compared to 12C plan in terms of liver sparing. Top: nominal scenarios, bottom: worst-case scenarios.
