ABSTRACT: objectives To compare the scientific methodology and
quality of articles published in Anales Espanoles de Pediatria and
Medicina Clinica.
Material and methods A stratified and randomized selection of 40 original
articles published in 2001 in Anales Espanoles de Pediatria and Medicina
Clinica was made. Methodological errors in the critical analysis of
original articles (21 items), epidemiological design, sample size,
statistical complexity and levels of scientific evidence in both journals
were compared using the chi-squared and/or Student's t-test.
Results No differences were found between Anales Espanoles de Pediatria
and Medicina Clinica in the critical evaluation of original articles (p >
0.2). In original articles published in Anales Espanoles de Pediatria,
the designs were of lower scientific evidence (a lower proportion of
clinical trials, cohort and case-control studies) (17.5 vs 42.5%, p =
0.05), sample sizes were smaller (p = 0.003) and there was less
statistical complexity in the results section (p = 0.03).
Conclusions To improve the scientific quality of Anales Espanoles de
Pediatria, improved study designs, larger sample sizes and greater
statistical. complexity are required in its articles.

ABSTRACT: Objectives To quantify the impact factor of Anales
Espanoles de Pediatria from 1997 until 2000 and to identify the journal's
citation patterns and the topics with the greatest impact.
Methods SCISEARCH was used to locate citations of articles published in
Anales Espanoles de Pediatria between 1995 and 1999. The following data
were collected for each article: year of publication, authors, journal,
country of publication, language, specialty or specialties,
institution(s), residence of the first author and topic. The impact
factor was calculated as the ratio between citations received over 1 year
by articles published in Anales Espanoles de Pediatria in the two
previous years and the total number of articles published by Anales
Espanoles de Pediatria over the 2 years under study.
Results The Impact factor of Anales Espanoles de Pediatria was 0.052 in
1997, 0.080 in 1998, 0.101 in 1999, 0.089 in 2000 and 0.064 in 2001.
Citations were found in a wide range of source journals. The greatest
proportion (35.6%) were found in Spanish medical journals. Citations were
made mainly by Spanish authors (62.8%) and self-citation was moderate
(14.3%). Topics related to neurology (16.9% of the citations received),
infectious diseases (16.2%) and neonatology (14.8%) had the greatest
impact.
Conclusion The impact factor of Anales Espanoles de Pediatria is modest,
although higher than that of some other biomedical publications included
in journal Citation Reports.

ABSTRACT: Background One important objective of Anales Espanoles de
Pediatria (An Esp Pediatr) is to be included in journal Citation Reports-
Science Citation index and the main step to achieve this is to increase
the scientific quality of this Spanish journal. Bibliometric indicators
are important tools used to determine the quality of scientific
publications.
Material and methods A bibliometric study of all the original articles
published in An Esp Pediatr in 2001 (n = 76) was performed; bibliometric
indicators were classified into quantitative and qualitative (statistical
analyses and level of scientific evidence). The results were compared
with the original articles published in the journal from 1994 to June
2000 (n = 733) and with the original articles published in Pediatrics in
2001 (n = 276).
Results The differences found in An Esp Pediatr between the two study
periods were the following in 2001: greater collaboration between
epidemiologists and/or biostatisticians in the authorship of articles
(19.7%), increased complexity of statistical analyses (statistical
accessibility > 7 in 25%) and greater use of evidence-based
methodological concepts (19.7%). However, no improvement was found in the
scientific evidence (evidence was good in only 1.4% and average in
25.7%). Other aspects of interest were a lower number of original
articles (due to an increase in other types of articles, such as Letters
to the Editor or Special Articles) and a greater percentage of articles
on evidence-based medicine or articles, using its methodology. The
differences in bibliometric indicators of quality found between An Esp
Pediatr and Pediatrics continued to be considerable: statistical
accessibility, evidence-based methodological concepts and scientific
evidence (for example, good evidence was 22 times more frequent in
Pediatrics).
Conclusions The scientific quality of An E p Pediatr improved in 2001
compared with that of previous years, but the differences found between
this journal and the gold standard of Pediatrics are still considerable.
We found greater interest in articles related to the new scientific
paradigm of evidence-based medicine, which uses the medical literature
more effectively to guide medical practice.

ABSTRACT: Objectives To assess and compare the scientific pediatric
production of Spanish authors in Pubmed and journal Citation Reports
(JCR) between 1996 and 2001.
Material and methods We reviewed the first 200 articles that appeared in
PubMed between 1996 and 2001 on childhood ("newborn OR neonate OR
children OR child OR infant") by Spanish authors (Spain [affiliation]).
We compared the quality of study design, sample sizes, subject of the
article, impact factor and the authors' specialty, using the chi-squared
and/or Student's t-test. The factors related to publication in journals
with an impact factor of more than 2 were analyzed using logistic
regression analysis.
Results Only 35% of the articles selected were performed exclusively in
children. Between 1996 and 2001, Spanish pediatric publications included
in the journal Impact Factor increased by 37.5%. The impact factor
between these two years was similar (1.776 vs 1.823; p: NS). An impact
factor of more than 2 was related to articles published in non-pediatric
journals (OR: 3, 95% CI: 1.17-7-69, p = 0.018), publications including
multiple regression analysis in the statistical analysis (OR: 3.27; 95 %
CI: 1.12-9-56; p = 0.028), multicenter studies (OR: 4.2, 95 % CI: 1.1-
22.4, p = 0.048) and articles on immunology or molecular biology (OR:
2.45; 95 % CI: 1.01-5.92; p = 0.044).
Conclusions In the last 5 years Spanish pediatric publications in
journals included in the JCR increased by 37.5%. We should promote
publications with larger sample sizes, multicentric studies and those
with high quality design (clinical trials and cohort studies).
