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.
