a Dotplots demonstrating the association of tumour volume and T-size with loco-regional failure (LRF) with the patient with the large volume outlier removed from both analyses: The horizontal black lines represent the median tumour quantification values; the dashed black lines represent the limits of the interquartile range. The y-axis has been standardised so that the medians in the controls are aligned (b): Receiver Operator Characteristic curves comparing the discriminatory performance of measured tumour volume and mrT-size. ^*AUCs compared by the method of DeLong et al.
