  1. *Articles abstracted are those that pass methodological criteria and are deemed to be the most important by practicing internists. The other articles listed are articles with the same high-quality methods but are considered to be slightly less important clinically by practicing clinicians; **The number of articles needed to read (NNR) is a measure of the ratio of number of relevant articles (abstracted or combined abstracted or listed) divided into the total number of articles for each journal title; ***SCI Impact Factors not available for analysis; ****Canada Coordinating Office for Health Technology Assessment Reports; N.A.
