Building on previous work (Pigott et al. 2014), estimates of areas of potential transmission of Ebola virus are revised and updated to provide a contemporary map for use by researchers and policymakers.
An analysis of more than 70,000 journal articles, including 5405 that were first released as a preprint on bioRxiv, shows that articles with a preprint received 49% more attention and 36% more citations than articles without one.
Publication bias, in which positive results are preferentially reported by authors and published by journals, can restrict the visibility of evidence against false claims and allow such claims to be canonized inappropriately as facts.
A simulation study is used to demonstrate how mistakes in identifying the experimental unit and the unit of analysis can lead to incorrect analyses and inappropriate inferences when reporting research studies.
