AB Objective. The objective of this study was to identify the
   journals that contain the best evidence relating to clinical
   pediatric practice, thus enabling general pediatricians and
   pediatric trainees to identify the best quality evidence more
   efficiently and to select journals for general reading more
   judiciously. Methods. In the first of three strategies, journal
   citations from completed systematic reviews using topic
   headings of pediatric(s), child, infant(s), newborn,
   neonate(s), neonatology, and adolescent(s) in the Cochrane
   Database of Systematic Reviews (CDSR) in the 1997, Issue 4,
   Cochrane Library were collected. In the second strategy,
   journal citations from American Academy of Pediatrics' (AAP)
   policy statements from 1994 to 1996 found in the AAP policy
   reference guide were collected. In the third strategy, journal
   citations from the Canadian Paediatric Society (CPS) statements
   from 1990 to 1997 found in Pediatrics and Child Health were
collected. Topics related to tertiary neonatology, nonphysician
   health care professionals, public health policy, ethics, and
   non-journal citation sources were excluded. All statements with
   no references were excluded. Journal citations in CDSR with no
   pediatric subjects and citation of AAP policy statements cited
   in AAP policy statements were excluded. The number of citations
   from the journal cited most frequently, from journals that
   represented similar to 10% of all citations and from the 10
   journals cited most frequently were expressed as a percent of
   total citations and a 95% CI was calculated. Results. Using all
   three strategies (CDSR, AAP, and CPS), the journal cited most
   frequently was Pediatrics. Using the CDSR strategy (n = 234),
   citations from Pediatrics represented 6.0% of the total (95%
   CI: 3.0%, 9.0%), using the AAP strategy (n = 930), citations
 from Pediatrics represented 11.4% of the total (95% CI: 9.4%,
   13.4%), and using the CPS strategy (n = 873), citations from
   Pediatrics represented 11.9% of the total (95% CI: 9.8, 14.1).
Using the CDSR strategy, citations from the 10 journals cited
   most frequently made up 38.9% of the total citations (95% CI:
   32.7%, 45.1%), using the AAP strategy, citations from the 10
   journals cited most frequently made up 42.3% of the total
   citations (95% CI: 39.3%, 45.3%), and using the CPS strategy,
   citations from the 10 journals cited most frequently made up
   60.6% of the total citations (95% CI: 57.4, 63.8). In the CPS
   strategy, citations from the Journal of Pediatrics represented
   10.2% of the total citations (95% CI: 8.2, 12.2) and citations
   from New England Journal of Medicine represented 9.5% of the
   total citations (95% CI: 7.6, 11.5). A total of 7 journals were
   found to be among the 10 cited most frequently using all three
   strategies (in alphabetical order): Archives of Diseases in
   Childhood, British Medical Journal, Journal of the American
   Medical Association, Journal of Pediatrics, Lancet, New England
   Journal of Medicine, and Pediatrics. Conclusions. This study
   provides the general pediatrician and pediatric trainee with a
strategy to identify efficiently a significant proportion of
   the best evidence on pediatric practice by restricting searches
   and reading to a limited number of journals. It also highlights
   the fact that the best quality evidence on pediatric practice
   is found in a large number of medical journals.
