Trial profile
IMRT=intensity modulated radiotherapy. *One patient was not randomised because the standard plan was unacceptable, owing to a significant region of low dose, so IMRT was prescribed; patient was withdrawn from the late toxicity analysis.

3. Figure 2
Q-Q plots showing p values (and corresponding χ2 values) obtained from (A) univariate and (B) multivariable analyses of overall toxicity against genotype at the 92 SNPs
The solid lines represent the identity line (x=y). p values do not vary significantly from those that would be expected from chance alone. SNP=single nucleotide polymorphism. df=degree of freedom.
