The relationship between age and emergency admission was U-shaped: more likely in patients aged &lt;25 years and \u226570 years. Compared to patients admitted via other routes, those presenting as an emergency had more advanced disease and poorer 3-year survival (relative survival 68.4% [95% confidence interval {CI} = 60.3 to 75.2] versus 89.8% [95% CI = 87.0 to 92.0], respectively [<jats:italic>P<\/jats:italic>&lt;0.01]).
