Fig. 2. — Incidence of radiation pneumonitis (RP) and V5 at 50.4 Gy. The solid curve represents the fit of the logistic model to the data. The solid dots represent the observed incidence of RP in 5 subgroups (for each; n = 17 or 18) plotted at the mean value of V5. The horizontal error bars represent the 95% confidence interval of the mean V5 in each group. The vertical error bars represent the 95% confidence interval of the incidence of RP by the score method.
