Use of automated external defibrillator by first responders in out of hospital cardiac arrest: prospective controlled trial

We inadvertently reversed two numbers in figure 1 of this paper by Anouk P van Alem and colleagues (BMJ 2003;327:1312-5). In the experimental group, 82 of the 157 participants in the “initial rhythm shockable” category were admitted to hospital. This represents 52% (not 25% as we stated).
