Análisis cienciométrico de la producción científica del Instituto Nacional de Cancerología / National Cancer Institute scientific production scientometric analysis

Resumen Introducción: La cienciometría permite analizar la productividad e impacto de las publicaciones científicas mediante técnicas bibliométricas y computacionales. Objetivo: Proponer una metodología multidimensional para obtener el perfil cienciométrico del Instituto Nacional de Cancerología (INCan), México, y compararlo respecto a otras instituciones nacionales de salud. Método: Con el programa LabSOM y la metodología ViBlioSOM, basada en redes neuronales artificiales, se analizó la producción científica del INCan indexada en la Web of Science entre 2007 y 2017. Se obtuvo el perfil cienciométrico multidimensional del Instituto y se comparó con el de otras instituciones nacionales de salud. Resultados: En productividad, el INCan ocupa el cuarto lugar de las 10 instituciones mexicanas de salud pública indexadas en la Web of Science.; en el ranking de impacto normalizado, el sexto lugar. Aun cuando de 1323 artículos, 683 (51.62 %) no recibieron citas, 11 artículos de excelencia (0.83 %) lograron 24 % de 11 932 citas y, consecuentemente, el impacto normalizado del INCan evidenció una productividad media por arriba de la media mundial. Conclusión: El análisis multidimensional con la red neuronal propuesta permite obtener un perfil cienciométrico institucional absoluto y relativo más fidedigno e integral que el derivado de conteos de variables aisladas.

Abstract Introduction: Scientometrics analyzes scientific publications through bibliometric and computational techniques, whereby productivity and impact indicators are generated. Objective: To propose a multidimensional methodology in order to obtain the scientometric profile of the National Cancer Institute (INCan), Mexico, and rank it with regard to other national health institutions. Method: Using the LabSOM software and the ViBlioSOM methodology based on artificial neural networks, the INCan scientific production indexed in the Web of Science from 2007 to 2017 was analyzed. The multidimensional scientometric profile of the Institute was obtained and compared with that of other national health institutions. Results: In terms of productivity, INCan ranks fourth among the 10 Mexican public health institutions indexed in the Web of Science; in the normalized impact ranking, it ranks sixth. Although out of 1323 articles 683 (51.62 %) did not receive citations, 11 articles classified as excellent (0.83 %) obtained 24 % of 11,932 citations and, consequently, INCan normalized impact rate showed a mean productivity higher than the world mean. Conclusion: Multidimensional analysis with the proposed neural network enables obtaining a more reliable and comprehensive absolute and relative institutional scientiometric profile than that derived from measuring isolated variables.

Búsqueda manual y electrónica de ensayos clínicos en revistas médicas cubanas: análisis de la terminología utilizada en su descripción / Manual and electronic search of clinical trials in Cuban medical journals: analysis of terminology

INTRODUCCIÓN Los ensayos clínicos se consideran la regla de oro para evaluar la eficacia y seguridad de las intervenciones. De manera independiente, pueden no ser suficientes para generalizar resultados, pero constituyen la base de revisiones sistemáticas que sintetizan sus resultados y suelen aportar evidencias de mayor calidad. Pero una vez publicados, la pobre descripción del método científico y el uso insuficiente de palabras clave, dificultan su recuperación por búsqueda electrónica y se requiere de la búsqueda manual. OBJETIVOS Comparar la capacidad de recuperación entre la búsqueda manual y estrategias múltiples de búsqueda electrónica para localizar ensayos clínicos en revistas médicas cubanas, y determinar la terminología utilizada para describir el ensayo clínico. Métodos Se combinó la búsqueda electrónica en la biblioteca virtual Scientific Electronic Library Online de Cuba (SciELO Cuba), y la base de datos de bibliografía médica cubana Cumed con la búsqueda manual utilizando la guía de búsqueda de Cochrane, para localizar los ensayos en tres revistas cubanas en el período 2000 a 2012. Se identificaron los términos significativos incluidos en título, resumen, palabras clave y métodos de cada artículo según la guía Cochrane, CONSORT y el tesauro de ciencias de la salud. RESULTADOS Se identificaron 50 ensayos en la búsqueda manual, de ellos cuatro coincidieron en la búsqueda electrónica; todos a través de SciELO Cuba (8%) y ninguno en Cumed. Las secciones menos descriptivas fueron el título y las palabras clave. Se utilizaron más palabras clave que descriptores autorizados; los únicos conceptos empleados en más de la mitad de los estudios fueron: "controlado" (60%) y "grupos de estudio" (52%); "aleatorizado" fue usado en el 50% de los artículos. Aunque son más específicos, no fueron muy usados los términos "ensayo clínico", "fase" y "código del ensayo". CONCLUSIONES La búsqueda electrónica es insuficiente para la identificación de ensayos clínicos respecto de la búsqueda manual. Por lo tanto, se precisa la combinación de ambos métodos para lograr un mayor índice de recobrado. La terminología usada para describir los ensayos clínicos en las revistas seleccionadas fue deficiente, debido a la subutilización del tesauro de ciencias de la salud.

INTRODUCTION Clinical trials are the gold standard for testing the efficacy and safety of interventions. On their own they may not be enough to reach definitive conclusions, but they are the basis for systematic reviews that synthesize the results of several studies. However, once clinical trials have been published, a poor description of the study design and lack of specific key words and descriptors make it difficult to retrieve them by electronic searches, thus requiring hand searching. OBJECTIVES To compare the retrieving capacity between hand search and the multiple strategies of electronic searches for identifying clinical trials in Cuban medical journals, and to determine the terminology used for describing these studies. METHODS We combined electronic searches in the Scientific Electronic Library Online of Cuba (SciELO Cuba) and Cuban database Cumed with hand search using the Cochrane guide to locate trials in three Cuban journals in the period 2000-2012. We identified the significant terms included in the title, summary, keywords and methods of each article according to Cochrane, CONSORT, and the health sciences thesaurus. RESULTS We identified 50 trials by hand search; four of them were retrieved by electronic search through SciELO Cuba (8%) while none was found through Cumed. The less descriptive sections were the title and the keywords. More keywords than authorized descriptors were used; the only specific concepts used in over half of the retrieved trials were "controlled" (60%), and "study groups" (52%); "randomized" was used in 50% of the retrieved documents. While more specific, the terms "clinical trial", "phase", and "clinical trial registration" were not used. CONCLUSIONS Compared to hand searching, electronic searches are insufficient to identify clinical trials. Therefore, the combination of the two meth-ods is necessary to reach higher retrieval rates. The terminology used to describe clinical trials in the selected journals was deficient due to underutilization of the health sciences thesaurus.

Publicación de los trabajos presentados a los congresos científicos de estudiantes de medicina, Perú 2002-2009: características y factores asociados. / Publication of summaries presented at the scientific congresses of medical students, Peru 2002-2009: characteristics and related factors.

Objetivos. Determinar la proporción de publicación de los resúmenes presentados a los congresos científicos nacionales de estudiantes de medicina de Perú entre los años 2002 y 2009 y sus factores asociados. Materiales y métodos. Se realizó una cohorte retrospectiva, se evaluó las características de todos los resúmenes presentados y se determinó si habían sido publicados en revistas científicas utilizando una estrategia de búsqueda validada con Google Académico. Se calculó los riesgos relativos (RR), crudos y ajustados mediante la regresión de Poisson con varianza robusta para evaluar asociación con los factores analizados. Resultados. Se analizó 532 resúmenes; 52 (9,8%) fueron publicados en revistas científicas luego de su participación en el congreso; en todos los casos fue en revistas peruanas y en español. La principal revista donde se publicaron fue (CIMEL) (13/52). La mediana del tiempo de publicación fue de 13 meses (rango: 0-75). El que un alumno de la Universidad Nacional Mayor de San Marcos (RR: 5,18; IC95%:2,3-11,6) sea autor del resumen y que el resumen sea de autoría colaborativa entre alumnos de dos universidades (RR: 3,64; IC95%:1,1-11,7) son factores asociados en el análisis multivariado. Conclusiones. La proporción de publicación de resúmenes presentados a los congresos científicos nacionales de estudiantes de medicina de Perú es baja. Se deben implementar nuevas medidas y reforzar las existentes para incentivar una mayor publicación de los trabajos presentados.

Objectives. To determine the publication rate of abstracts submitted at the national scientific meetings of medical students in Peru between 2002 and 2009, and associated factors. Materials and methods. A retrospective cohort was performed; the characteristics of overall abstract submitted were assessed. In addition, whether they were published in scientific journals was determined by way of a search strategy validated using Google Scholar. Crude and adjusted relative risks (RR) were calculated using Poisson regression with robust variance to assess association with the analyzed factors. Results. 532 abstracts were analyzed, 52 (9.8%) of which were published in scientific journals after their presentation at a scientific meeting. All of them were published in Peruvian journals written in Spanish. The most important journal in which they were published was Ciencia e Investigación Médica Estudiantil Latinoamericana (CIMEL) (13/52). The median of publication time was 13 months (range: 0-75). The fact that a student from the Universidad Nacional Mayor de San Marcos (RR: 5.18; CI95%:2.3-11.6) is the author of the abstract and that the abstract was collaboratively written by students from two universities (RR: 3.64; CI95%:1.1-11.7) are associated factors in the multivariate analysis. Conclusions. The publication rate of abstract submitted at national scientific meetings of medical students in Peru is low. New strategies should be taken, and the existing ones should be reinforced in order to increase the publication rate of the abstract submitted.

Evaluation of the key words used in articles of the Acta Cirurgica Brasileira from 1997 to 2012 / Avaliação dos descritores utilizados nos artigos da Acta Cirúrgica Brasileira de 1997 a 2012

PURPOSE: To evaluate the key words used in Acta Cirurgica Brasileira from 1997 to 2012. METHODS: All the key words of all articles published in regular issues between 1997 and 2012 were analyzed, ensuring that these key words were in the MeSH database (Medical Subjects Headings) and the most used subject headings and most wrong repeated key words were ranked. RESULTS: > 4230 key words used in 990 articles were analyzed. Only 579 key words (13.68%) were not in the MeSH database, considering that there was a statistically significant decrease over the years (p<0.001). The three most used key words were Rats, Dogs and Wound healing. Among the wrong ones, the key words were Adhesions, Experimental surgery and Anatomosis. CONCLUSION: There was a gradual improvement in the amount of key words used that belonged to the MeSH database, and there were 618 articles (62.42%) with all key words correct.

OBJETIVO: Avaliar os descritores utilizados na Acta Cirúrgica Brasileira entre os anos de 1997 até 2012.

RESULTADOS: Foram analisados 4230 descritores, presentes em 990 artigos. Apenas 579 (13,68%) dos descritores estavam fora da base do MeSH, sendo que houve uma diminuição estatisticamente significante com o passar dos anos (p<0.001). Os três descritores mais utilizados foram Rats, Dogs e Wound healing, já dentre as equivocadas foram os termos Adhesions, Experimental surgery e Anatomosis. CONCLUSÃO: Houve uma melhora progressiva na quantidade de termos utilizados que pertenciam a base do MeSH, havendo 618 artigos (62,42%) com todos os descritores corretos.

The production of articles on cardiology from Latin America in Medline indexed journals / La producción de artículos cardiológicos latinoamericanos indizados en Medline

Introduction: Latin America has dramatically increased the number of articles published from 1995 to 2002, but the individual contribution of each country appears to be very unequal. Objectives: To analyze the production of articles on Cardiology research published in Latin American countries in the past years in international journals. Methods: A bibliography search was carried out throughout PubMed in regards to biomedical articles in general and on Cardiology in particular, corresponding to the period 1987 - 2006. Results: A total of 106 871 biomedical articles was identified, and 11 416 on Cardiology published between 1997 and 2006 by Latin American countries. This corresponds to 10.6% of articles on cardiovascular disease over the total. Brazil, Mexico and Argentina contributed with 80% of the publications in Latin America in the same period. The magnitude of growth since 1987 was between 5.9- and 15-fold for these countries. In regards to Brazil, since 1998 a significant increased number of publications was noted compared to Mexico and Argentina (P = 0.0001). The impact factor of the journals where each country published during 2006 showed that it was in average higher in the publications from Chile and Argentina compared to Brazil and Mexico (P <0.001). Conclusions: The scientific production in Cardiology from Latin America shows dramatic differences among the countries, and Brazil, Mexico, and Argentina alone provide 80% of the publications. Brazil seems to have led the region for 20 years, especially since 1998. From the quality of the articles point of view, considering the impact factor, Chile and Argentina appear to be better positioned.

Introducción: La estimación de la producción científica en enfermedades cardiovasculares indica que América Latina incrementó el número de artículos publicados desde 1995 hasta 2002, pero la contribución individual de cada país parece ser desigual. Objetivo: Analizar la producción de artículos de investigación cardiológica publicados por los países latinoamericanos en revistas internacionales. Métodos: Se realizó una búsqueda bibliográfica en PubMed de artículos biomédicos y cardiológicos. Correspondientes al periodo de 1987 a 2006. Resultados: Se identificaron 106 871 artículos biomédicos y 11 416 cardiológicos (10.6%) publicados entre 1997 y 2006 por países latinoamericanos. En orden de importancia, Brasil, México y Argentina contribuyeron con 80% de las publicaciones. La magnitud del crecimiento de los artículos cardiológicos desde 1987 estuvo entre 5.9 y 15 veces para estos tres países. En Brasil se observó a partir de 1998, un aumento significativo del número de publicaciones con respecto a México y Argentina (P = 0.0001). El factor de impacto de las revistas en que publicaron sus artículos cardiológicos cada país durante 2006 mostró que éste fue en promedio superior en las publicaciones de Chile y Argentina con respecto a Brasil y México (P <0.001). Conclusiones: La producción científica cardiológica de América Latina tiene marcadas diferencias entre los países, y solamente Brasil, México y Argentina aportan 80% de lo publicado. Brasil lidera la región desde hace 20 años; en cuanto al factor de impacto, Chile y Argentina parecen estar mejor posicionados. Esta información serviría para conocer la situación individual de cada país y para establecer políticas de promoción científica.

A map of Brazilian dental research in the last decade

The aim of the present study was to analyze dental research trends in Brazil over the past nine years. All abstracts presented at the 26th Annual Meeting of the Brazilian Society for Dental Research in 2009 (n = 2648) were classified based on field of knowledge, home institution and geographic region. Data were compared with those previously published based on abstracts presented at various meetings. Between 2001 and 2006, five fields of knowledge had a greater than 10 percent representation among the total number of studies. These fields included restorative dentistry/dental materials (RD/DM), periodontics, endodontics, pediatric dentistry and population-based oral health. In 2009, only RD/DM maintained a greater than 10 percent proportion of meeting abstracts, and basic fields comprised the second position among those fields with greater representation (9.8 percent). The majority of research studies were performed at public institutions, and the number of abstracts per state increased significantly in 2009 (Wilcoxon test, p < 0.001). The southeastern region of Brazil submitted the greatest number of abstracts; however, other regions also demonstrated increased participation in research (11 percent). The percentage distribution of abstracts between states remained constant (Wilcoxon test, p = 0.255; r s = 0.873). The results of the present study suggest a slight shift in the scientific research profile in Brazilian dentistry: fields related to professional disciplines have declined in relative research participation, while increasing interest has been observed in basic fields and new specialties.

MÉTODOS: Estudo prospectivo observacional dos resumos publicados nos Anais do Congressos Brasileiro de Cirurgia Torácica - Tórax 2009, para descrição quantitativa e qualitativa da distribuição geográfica e do tipo das instituições de origem dos resumos, dos tipos de estudos e dos temas abordados. RESULTADOS: Foram publicados 182 resumos, sendo 174 (95,60%) intervencionistas. Houve três resumos provenientes de instituições estrangeiras, todos provindos de uma mesma instituição italiana. Quanto aos tipos de estudos, foram observados 108 estudos clínicos, 67 relatos de caso e sete estudos experimentais. No cômputo geral, a ressecção pulmonar (14,29%) é o tema mais freqüente, seguidos de câncer pulmonar, hiperidrose e afecções traqueais (10,44%), trauma torácico (7,14%) e mediastino (6,04%). As instituições públicas participaram com 68,16% dos resumos avaliados, as instituições privadas 11,17% e as chamadas institucionais com 20,67%, sendo que as Pontifícias Universidades Católicas (11,00%) e as Santas Casas (7,70%) tiveram participação significativa na pesquisa em Cirurgia Torácica no Brasil. CONCLUSÃO: As instituições públicas são as principais responsáveis pela atividade de pesquisa em Cirurgia Torácica no Brasil, a qual está mais concentrada no estado de São Paulo (34,07%). Um terço desta atividade é representada por relatos de caso e, embora haja grande variação de assuntos abordados, a ressecçãos pulmonar é o tema mais freqüente.

OBJECTIVE: To increase the knowledge of research activity in Thoracic Surgery in Brazil. METHODS: We carried out a prospective observational study of the abstracts published in the Annals of the Brazilian Congress of Thoracic Surgery - Thorax 2009, to quantitatively and qualitatively assess the geographic distribution and type of home institutions of abstracts, the types of studies and themes addressed. RESULTS: We published 182 abstracts, 174 (95.60%) of interventionist nature. There were three foreign abstracts, all from a single Italian institution. As for the types of studies, we observed 108 trials, 67 case reports and seven experimental studies. Pulmonary resection (14.29%) was the most frequent theme, followed by lung cancer, hyperhidrosis and tracheal disorders (10.44%), trauma (7.14%) and mediastinum (6.04%). Public institutions participated with 68.16% of the abstracts, private institutions with 11.17% and the philanthropic entities with 20.67%; the Pontifical Catholic Universities (11.00%) and the Santas Casas - Holy Homes (7.70 %) - had a significant involvement in Thoracic Surgery research in Brazil. CONCLUSION: Public institutions are mainly responsible for research activity in Thoracic Surgery in Brazil, which is more concentrated in the state of São Paulo (34.07%). One third of this activity is represented by case reports and, although there is wide variation in topics covered, pulmonary resection is the most frequent theme.

Epidemiologia e saúde coletiva: tendências da produção epidemiológica brasileira quanto ao volume, indexação e áreas de investigação - 2001 a 2006 / Epidemiology and public health: tendencies of the Brazilian epidemiology production regarding volume, indexation and investigation areas - 2001 a 2006

O presente artigo examina e interpreta as tendências da produção epidemiológica no Brasil, no contexto da Saúde Coletiva. Utilizou-se, como banco de dados, os Cadernos de Indicadores da Capes, no período de 2001 a 2006. Foram analisados 26 programas, sendo que os dez maiores tiveram sua produção bibliográfica em periódicos indexados examinada. Observou-se que a produção total de artigos epidemiológicos representou 40 por cento da produção em Saúde Coletiva e 55 por cento da produção em revistas internacionais, destacando-se Cadernos de Saúde Pública, Revista de Saúde Pública e Ciência & Saúde Coletiva. Os temas mais prevalentes foram nutrição em saúde pública, saúde materno-infantil e doenças infectocontagiosas, particularmente a aids. Saúde-trabalho-ambiente, saúde oral, violência e saúde do idoso vêm se consolidando como objeto de estudo da disciplina, enquanto estudos de meta-análise e geoprocessamento aparecem como ferramenta útil para os serviços de saúde. Conclui-se que há tendência de aumento da produção epidemiológica em publicações indexadas, abrangendo temáticas diversas e abarcando amplo espectro de aspectos relevantes para a política de saúde no país.

This article examines and interprets the trends of epidemiological production in Brazil in the Public Health context. CAPES indicators from 2001 to 2006 were used as database. We analyzed 26 programs and select the 10 major ones to analyze their bibliographic production in indexed journals. It was observed that the total production of epidemiological articles accounted for 40 percent of production in Public Health and 55 percent of the production was published in international journals, especially Cadernos de Saúde Pública, Revista de Saúde Pública and Ciência & Saúde Coletiva. The most prevalent themes were public health nutrition, maternal and infant health and, infectious diseases, particularly AIDS. Environmental e worker's heath, oral health, violence and health of the elderly have been ratified as objects of study for the discipline, while meta-analysis and geoprocessing appear as a useful tool for health services. We conclude that the epidemiological production tends to increase in indexed publications, covering various topics and a wide spectrum of relevant issues to Brazilian health policy.

Evaluation of scientific periodicals and the brazilian production of nursing articles / La evaluación de periódicos científicos qualis y la producción brasileña de artículos del área de enfermería / A avaliação de periódicos científicos qualis e a produção brasileira de artigos da área de enfermagem

This study aimed to identify nursing journals edited in Brazil indexed in the main bibliographic databases in the areas of health and nursing. It also aimed to classify the production of nursing graduate programs in 2007 according to the QUALIS/CAPES criteria used to classify scientific periodicals that disseminate the intellectual production of graduate programs in Brazil. This exploratory study used data from reports and documents available from CAPES to map scientific production and from searching the main international and national indexing databases. The findings from this research can help students, professors and coordinators of graduate programs in several ways: to understand the criteria of classifying periodicals; to be aware of the current production of graduate programs in the area of nursing; and to provide information that authors can use to select periodicals in which to publish their articles.

The publication rate of abstracts presented at the 2003 urological brazilian meeting

OBJECTIVE: To determine the publication rate of orally-presented abstracts from the 2003 Urological Brazilian Meeting, as well as the factors determining this publication rate. MATERIALS AND METHODS: The publication rate of the 313 orally-presented abstracts at the 2003 Urological Brazilian Meeting was evaluated by scanning the Lilacs, Scielo and Medline databases. The time between presentation and publication, the state and country of the abstract, the research methodology (cross-sectional, case-control, retrospective case series, prospective case series or clinical trial), whether drugs were utilized and the topic of the study were all characterized. RESULTS: Thirty-nine percent of the abstracts were published after a median time of 14 months (range: 1 to 51 months). There were high publication rates for cross-sectional abstracts (75 percent), drug utilization studies (51.3 percent), clinical trials (50 percent) and prospective case series' (48.1 percent). However, there was only a moderate statistical trend towards a higher publication rate in the prospective case series (p=0.07), while the retrospective case series' showed statistically lower publication rates than the other groups (33.7 percent, p=0.04). Abstracts on laparoscopic surgery had the highest publication rate (61.9 percent, p=0.03) compared to others topics. In 57 percent of the unpublished abstracts, there was no interest in or attempt to publish, and rejection was responsible for the lack of publication of only 4 percent of the abstracts. CONCLUSION: The publication rate of the orally-presented abstracts from the 2003 Urological Brazilian Meeting was comparable to that of international congresses. The subsequent publication of presented abstracts and the selection of prospective studies with stronger evidence should be encouraged and may improve the scientific quality of the meeting.

An observational study of the proceedings of the All India Ophthalmological Conference, 2000 and subsequent publication in indexed journals.

AIMS: To determine the quality of reporting in the proceedings of the All India Ophthalmological Conference (AIOC) 2000, subsequent rate of publication in an indexed journal and differences between the proceedings and the journal version of these papers. DESIGN: Observational study. MATERIALS AND METHODS: All papers presented at the AIOC 2000 were retrieved from the proceedings and assessed for completeness of reporting. To determine the subsequent full publication, a Medline search was performed as of January 2007; consistency between the proceedings paper and the final publication was evaluated. Statistical analysis: Chi square and Fisher's exact tests were used to compare publication rates based on geographical location, subspecialty and study design; Student's t -test was used to compare differences based on the number of authors and sample size. RESULTS: Two hundred papers were retrieved; many failed to include study dates, design or statistical methods employed. Thirty-three (16.5%) papers were subsequently published in indexed journals by January 2007. The published version differed from the proceedings paper in 27 (81.8%) instances, mostly relating to changes in author name, number or sequence. CONCLUSIONS: The overall quality of reporting of scientific papers in the proceedings of the AIOC 2000 was inadequate and many did not result in publication in an indexed journal. Differences between the published paper in journals and in proceedings were seen in several instances. Ophthalmologists should be cautious about using the information provided in conference proceedings in their ophthalmic practice.

comparison of hand searching versus EMBASE searching of the Bahrain medical bulletin to identify reports of randomized controlled trial

The aim of this study is to identify reports of randomized controlled trials by hand searching the Bahrain Medical Bulletin and to determine the added value of the hand searching in minimizing the effects of indexing bias. All issues of the BMB were searched by hand from cover to cover for reports of trials. These were classified as randomized controlled trials [RCTs] or controlled clinical trials [CCTs] according to the Cochrane eligibility criteria. Photocopies of the bibliographic details and of the pages describing the study design of the reports identified were sent to the UK Cochrane Centre for verification and submission to the US Cochrane Center for publication in CENTRAL in The Cochrane Library. EMBASE and CENTRAL were also searched to identify if the reports found by the handsearch were already included in either of these databases. Sixteen trials out of 395 articles were identified, 12 RCTs and 4 CCTs. The added value of the handsearch in relation to EMBASE was 13 of the 16 [81%], and that for CENTRAL was 8 of 16 [50%]. Handsearching provides a valuable and unique contribution from the Arab region to the global effort by the Cochrane Collaboration. The handsearching of this journal, should help reviewers to minimize the effects of publication bias by providing reports of trials not previously identified. The handsearching has also ensured that reports of trials will not remain 'buried' because of indexing bias
