Table 3.

All centres combined data showing the absolute difference in bladder, rectal and PTV mean doses of the original and RP2 plans (OP-RP2) and associated standard errors. Positive values show reductions obtained using RP2, while negative values represent an increase in dose using RP2. Values in bold represent statistically significant differences.
