OBJECTIVES This report synthesises a subset of 31 journal articles on high-fidelity simulation-based medical education containing 32 research studies drawn from a larger qualitative review published previously. These studies were selected because they present adequate data to allow for quantitative synthesis. We hypothesised an association between hours of practice in simulation-based medical e...

A lthough sound authorship of biomedical journal articles relies on personal and professional integrity and accountability, recent controversies concerning ghostwriting and guest authorship have shown that this approach has limitations. Ghostwriting and guest authorship are often linked to academic-industry collaborations. Typically, industrysponsored professional writers prepare complete artic...

BACKGROUND Reporting guidelines have been available for the past 17 years since the inception of the Consolidated Standards of Reporting Trials statement in 1996. These guidelines were developed to improve the quality of reporting of studies in medical literature. Despite the widespread availability of these guidelines, the quality of reporting of medical literature remained suboptimal. In this...

BACKGROUND Reporting of health research is often inadequate and incomplete. Complete and transparent reporting is imperative to enable readers to assess the validity of research findings for use in healthcare and policy decision-making. To this end, many guidelines, aimed at improving the quality of health research reports, have been developed for reporting a variety of research types. Despite ...

This Article-in-Press has been permanently withdrawn. The editorial policy of Medical Hypotheses makes it clear that the journal considers "radical, speculative, and non-mainstream scientific ideas", and articles will only be acceptable if they are "coherent and clearly expressed."

The second set aims to increase ...
