# - sensitivity analysis was performed for the values shown in Table but also for all extreme values (0–1)- the change in the assumptions did not affect the results of the analysis; $- based on the survey of 8 clinical investigators; * assumed to be the same within and outside of the trial; MC- Monte Carlo; **- actual values based on reference [41] is 0.41 (0.37-0.45) for experimental and 0.59 (0.55-0.62) for standard treatment, respectively ***-based on the reference [41].
