The Impact Factor is always calculated by dividing the number of cites in the JCR year (in this case, 2004) to articles published in the previous two years (2002, 2003) by the number of article published in each of the two previous years. * In the case of Journal of Pediatrics, in 2004, the items published in 2002 were cited 846 times and the items published in 2003 were cited 784 times for a total of 1630 The Journal or Pediatrics published 255 articles/reviews in 2002 and 268 in 2003 for a total of 523 articles/reviews.

Utilice JCR prudentemente
No se debe depender solamente de los datos de citación de una revista. Los datos de citación no deberían reemplazar la evaluación por pares. Se debe prestar atención a las varias condiciones que influyen en el patrón de citaciones por ejemplo; idioma, historial de la revista, formato de la revista, horario de publicación, y temática especializada You should not depend solely on citation data in your journal evaluations. Citation data are not meant to replace informed peer review. Careful attention should be paid to the many conditions that can influence citation rates such as language, journal history and format, publication schedule, and subject specialty. The number of articles given for journals listed in JCR include primarily original research and review articles. Editorials, letters, news items, and meeting abstracts are usually not included in article counts because they are not generally cited. Journals published in non-English languages or using non-Roman alphabets may be less accessible to researchers worldwide, which can influence their citation patterns. This should be taken into account in any comparative journal citation analysis. For more information about how JCR is produced and factors affecting JCR data, please the sections “Information for New Users” and “Using JCR Wisely” in the Help File.

Utilice JCR prudentemente
El número de artículos dados por revistas listadas en JCR incluye investigaciones originales primarias y reseñas. No incluyen editoriales, cartas, documentos de la prensa y abstracts de reuniones, que por lo general, no reciben citas. Las revistas que no publican en inglés o que usan el alfabeto romano pueden ser menos accesibles para los investigadores globales y esto influye en su tasa de citas. Hay que tenerlo en cuenta cuando se hace una comparación de análisis de citaciones de revistas. You should not depend solely on citation data in your journal evaluations.
