Figure 1. As an example, the reference NTCP model for one of the reference populations (grey line) and its bootstrapped 95% CIs (grey area). The boxes represent the median NTCP of the models generated with dose errors and the error bars represent the 95% CIs.

Figure 2. The differences in NTCP between the NTCP models generated with dose errors and their respective reference NTCP model. The boxes represent the median and the error bars the 95% CIs.

Conclusion In the majority of the cases, 95% of the NTCPs from NTCP models generated with dose errors were within the 95% CI of the reference NTCP model. The larger dose error was associated with larger systematic underestimations of the NTCP for higher doses.
