Mortality and survival by age group in incident young adult RRT patients compared with the general population

	Crude mortality rate/1000 patient-years		Standardized mortality ratio	Cumulative survival
	Young adult RRT patients (95% CI)	Age-matched general populationa		Observed survival in young adult RRT patients	Relative survivalb (95% CI)
Age group (years)
11–< 16	6.77 (2.90–15.8)	0.14	49.9	0.961	0.962 (0.938–0.978)
16–< 21	13.8 (10.3–18.4)	0.38	36.0	0.924	0.926 (0.901–0.946)
21–< 26	19.4 (10.1–37.3)	0.48	40.8	0.899	0.902 (0.877–0.921)
26–30	24.2 (13.0–45.1)	0.58	41.9	0.876	0.899 (0.857–0.898)
Overall	18.0 (16.0–20.2)	0.40	45.1	0.905	0.908 (0.896–0.918)

^aUsing 2001–14 mortality data from the ONS, an equivalent period to the study follow-up (2000–13).

^bCumulative relative survival accounts for the background risk of dying in the age-matched general population [14].
