Odds ratios from univariate ordinal regression of distribution-adding VX and peak late toxicity. The toxicities are rectal bleeding (a), stool frequency (b), diarrhoea (c), anorectal pain (d) and urgency/tenesmus (e). The peak late toxicities for rectal bleeding and stool frequency were dichotomised at grade 2 whereas diarrhoea, anorectal pain and urgency/tenesmus were dichotomised at grade 1. A red dot is used to indicate the doses at which odds ratios are significantly different from a value of one (95 % confidence intervals do not include one). Abbreviations: VX, percentage of the rectal volume receiving at least X Gy after applying an α/β = 3 Gy; EQD2 Gy, equivalent dose in 2-Gy fractions using α/β = 3 Gy; 95 % CI, 95 % confidence interval
