EBM does not include a listing of important but not abstracted articles ("Other Articles Noted" section); *Articles abstracted are those that pass methodological criteria and are deemed to be the most important by a team of practicing general/family practitioners; **The number of articles needed to read (NNR) is a measure of the ratio of number of relevant articles (abstracted) divided into the total number of articles for each title; ***SCI Impact Factors not available for analysis; N.A. Not applicable. Data are for 2000. Note that the AHRQ/AHCPR reports were not considered journal titles and read as such for this report.
