<< Pain Management in the Emergency Department


Evidence-based medicine requires a critical appraisal of the literature based upon study methodology and
number of subjects. Not all references are equally robust. The findings of a large, prospective, randomized, and blinded trial should carry more weight than a case report.

To help the reader judge the strength of each reference, pertinent information about the study, such
as the type of study and the number of patients in the study, will be included in bold type following the reference, where available.
