Fatal food anaphylaxis incidence rates – calculated using different estimated food allergy prevalence rates

	Estimated food allergy prevalence*	Mean (95% CI) mortality rate (micromorts)
All fatal food anaphylaxis	Food allergy prevalence 4% [2]	1.35 (0.71, 2.59)
	Food allergy prevalence 3% [2]	1.81 (0.94, 3.45)
	Food allergy prevalence 2% [2]	2.71 (1.42, 5.17)
Fatal food anaphylaxis in young people (age 0–19)	Food allergy prevalence 10.4% [1]	1.18 (0.63, 2.22)
	Food allergy prevalence 3.9% [7]	3.25 (1.73, 6.10)
	Food allergy prevalence 2% [2]	6.13 (3.25, 11.56)
Fatal peanut anaphylaxis	Peanut allergy prevalence 2.9% [1]	0.73 (0.38, 1.43)
	Peanut allergy prevalence 1% [2]	2.13 (1.09, 4.16)
	Peanut allergy prevalence 0.5% [2]	4.25 (2.17, 8.31)

^*Estimated prevalence rates are taken from the meta-analysis of Rona et al. [2], for symptoms of food allergy and a positive allergy test, or for some estimates from more recent studies [1,7].
