^a #P and #T are the number of patients and tests, respectively. P($\overline{\text{R}}$), P($\overline{\gamma }$%), and P(${\overline{\gamma }}_{\text{mean}}$) correspond to the percentages of patients (P) within tolerance $\overline{\text{R}},\overline{\gamma }\text{\%},$ and ${\overline{\gamma }}_{\text{mean}}$ and T(R), T(γ%), and T(γ_mean) are the percentages of tests (T) within tolerance R, γ%, $\text{\%}$ and γ_mean, respectively. Of all, 355 of 3940 tests (9%) resulted in OTL. For the abdomen treatments, 2 percentage values are reported; the first 1 corresponds to the percentage considering all the errors (class 1 and class 2); the second was obtained omitting class-2 errors.
