Two different methods of article delivery to the biocurators were tested.
We felt this was unlikely, as most methods sections of articles tend to report the statistical techniques and datasets used.
We screened the methods sections of articles published in four major epidemiologic journals in 2008 (American Journal of Epidemiology, Epidemiology, European Journal of Epidemiology and the International Journal of Epidemiology) for a description of the technique used to select variables.
We also examined the acknowledgment and methods sections of articles meeting these criteria for indications of writing and editing assistance (see questions 13, 17, and 19 in the study questionnaire on bmj.com).
To assess the accuracy of a priori assumptions, we calculated relative differences between hypothesised parameters for the control group reported in the materials and methods sections of articles and estimated ones reported in the results sections.
The path extension method of article [9] could provide strong protection for source-location privacy, which performs quite well even though an object occurs near the base station.
Two main methods of review articles are commonly found in the scientific literature: systematic and narrative review of the literature.
Two methods of screening articles for inclusion in a systematic review were compared: titles first versus titles and abstracts simultaneously.
They range from simple preservation (such as sun drying) and operations closely related to harvesting to the production, by modern, capital-intensive methods, of such articles as textiles, pulp and paper.
