Validation of QUANTEC LKB NTCP model. Observed Gr2+ late GI toxicities agree with predictions based on QUANTEC18 recommended LKB parameters (dotted line). Dose-response curve obtained with parameters fitted to RTOG0126 data is shown for comparison (solid line). Vertical error bars are 68% binomial confidence intervals, error bars on effective dose values are standard deviations.
