From: The impact of contour variation on tumour control probability in anal cancer
Sensitivity analyses. a: Tumour control probability with changing N0, b: variation in tumour control probability between plans with changing N0, c: tumour control probability with changing dose, d: variation in tumour control probability between plans with changing dose. TCP = Tumour Control Probability, SD = Standard Deviation, N0 = number of initial clonogens, Gy = Gray, CTV54p = Primary clinical target volume to receive 54Gy, CTV54n = Nodal clinical targe volume to receive 54Gy, CTV45 = Elective clinical target volume to receive 45Gy
