These are the 104 terms used. The search engine was not case sensitive. The numbers in parentheses represent, respectively, the number of times that the term was identified in a discharge summary, the number of times that the context of the term was suggestive of an adverse event, and the number of times that the term was associated with a true adverse event, as determined by the gold standard method.
