The ratio of EQD2model over physical dose (EQD2model/Dphy) and the relative biological effectiveness (RBE) as a function of fractional dose of CIRT: (a) The EQD2model/Dphy, comparing the treatment efficacy of CIRT relative to the conventional photon RT, increases with the increase of fractional dose; (b) The RBE tend to decreases as the fractional dose increases. The error bars in both figures indicate the range of the ratio of EQD2model/Dphy or RBE values, when the parameters varied within 95% confidence intervals.
