Editor's Note: This 10th installment of Annals of Emergency Medicine Journal Club departs slightly from previous installments by focusing on a single methodological issue, the measurement of reliability. We use the Cruz et al article as a jumping-off point for our discussion.¹ Although this installment may be appropriate for some residency journal clubs (particularly if they use our more basic questions and add some clinical questions about the article), we suspect that it will be of greater value to research fellows and researchers.Readers should recognize that these are suggested answers and, although it is hoped that they are correct, are by no means comprehensive. There are many other points that could be made about these questions or about the article in general. Questions are rated “novice,” () “intermediate,” () and “advanced” ().
