Median distribution-adding DX% for the toxicity and no toxicity groups. The peak late toxicities for rectal bleeding (a) and stool frequency (b) were dichotomised at grade 2 whereas diarrhoea (c) and urgency/tenesmus (d) were dichotomised at grade 1. The red curve and p-value axis indicate doses at which median DX% values for the toxicity and no toxicity groups are significantly different (p-value < 0.05). Abbreviations: DX%, minimum dose to the most irradiated X percentage of rectal volume after applying an α/β = 3 Gy; EQD2 Gy, equivalent dose in 2-Gy fractions using α/β = 3 Gy
