↵a R2 statistic shows explained variation in time to diagnosis of gastro-oesophageal cancer—higher values indicate more variation is explained.
↵b D statistic is ameasure of discrimination—higher values indicate better discrimination.
↵c ROC statistic is ameasure of discrimination—higher values indicate better discrimination.
