List of Abbreviations

Medical literature is riddled with a seemingly endless amount of different abbreviations, as especially clinicians are particularly fond of using them. This article has been designed to help our readers find out what most used acronyms and abbreviations stand for. Naturally we haven't listed all the abbreviations one can find in EBM Guidelines, but hopefully the most useful ones.
