  1. Mean values and standard deviation of delivery time, monitor units and control points for FF and FFF mode averaged over all patients separated by the treatment technique. Bold values indicate statistically significant superior values in the comparison of FF vs FFF. Bold-italic letters indicate best values in the comparison of all planning techniques and irradiation modes. aindicates statistical significance in the comparison of FF vs FFF without judgement, since the number of monitor units and the number of control points are no measures of quality
