*Adjusted for calendar year, age and deprivation.
†Based on Wald test.
‡Emergency department data from 2011 onwards only.
§Deprivation: 1=most deprived; 5=least deprived.
¶Data collected in 2015 up until 30 September—denominator for incidence rate adjusted accordingly but actual counts may appear lower.
GP, general practice; IRR, incident rate ratio; PYAR, person years at risk.
