To do this, we fitted regression models for each article on the basis of the summary data (means, standard deviations, and sample sizes) using a modification of the method described by Larson (31).
Given the large number of articles included (n = 99), and the fact that our definitions of the types of training were inclusive, the first three authors read, classified, and compared their ratings for each article to ensure reliability of the results.
The grid allowed collection of the following data for each article: type of documents, country of origin of the study, research objectives, type of brokerage activities, recipient of the intervention, type of study, and research methods.
After reading the full texts of the selected articles, the following variables were noted separately for each article: details of the patients, number of centers participating in the study, name of the country where the study was performed, trial design, objectives of the trial, interventions, adverse effects detected in the trial, efficacy, and conclusions.
This measure can be easily calculated for each article, irrespective of the language, size, and length of its history.
Using Web of Science (Thomson Reuters, USA), we manually screened the reference lists of all published studies included in the meta-analysis and documented for each article which of the other included studies were cited.
For each article, sequences of HTML tags surrounding the phrases commonly found to be section headings in scientific publications (such as 'Abstract', 'Methods', 'Results') are collected; subsequently, all phrases surrounded by identical or similar tag sequences within the article are assumed to be section headings or subsection headings.
AND PUBYEAR AFT 1999 After the relevant articles were identified, selected fields including a unique identifier for each article, the year of publication, the number of citations, the article title, the journal title, the authors, the abstract, and the authors' affiliations were downloaded.
