Table 2 Incidence of out-of-hospital cardiac arrest resuscitation attempts per 100,000 population per year

From: Apples to apples: can differences in out-of-hospital cardiac arrest incidence and outcomes between Sweden and Ireland be explained by core Utstein variables?

  Ireland Sweden

  1. EMS Emergency Medical Services
  2. * Higher incidence in Sweden (p < =0.05)
  3. ** Higher incidence in Swedish males than Irish males (p < =0.05);
  4. a Higher incidence in Swedish females than Irish females (p < =0.05)
