Hospital admissions to Specialist Burns Units
Country comparison	England–Wales
P value	<0.001
IRR (95% CI)	0.6 (0.5 to 0.7)

P value	<0.001
IRR (95% CI)	1.2 (1.1 to 1.3)

General practice not available by country. NI mortality IRR are not calculated as there were no mortality burns cases in NI. For emergency attendances, there were insufficient data for other UK IRR. P values are derived from the incidence rate ratio command in Stata. We used the ‘midp’ one-sided exact significance calculated as a binomial probability.
