We conducted searches for all articles indexed in PubMed containing permutations of the phrases "functional magnetic resonance imaging," and "ethics," as well as all literature containing the term "neuroethics" specifically, and recorded publication numbers for each year (see Appendix A in Appendix S1).
Furthermore, we recorded publication information for each study, such as date of publication and journal.
From the identified studies and respective populations we recorded publication reference, total number of participants, country, sex, age (mean, median, or range), recruitment time, follow-up (years), outcome reported (stroke, cardiovascular disease) and method of outcome assessment, number (rate) of events, method of assessing salt intake, and level of salt intake in different categories.
To identify and assess trends in the development of LCA as a tool and the evolution of its scope and methodologies, we assessed the publication landscape for LCA in the Scopus database from the first recorded publication in 1978 through 2013.
One reviewer (R-JdV), blinded from the quality assessment, recorded publication data, number of participants, study design, diagnosis, intervention and, if applicable, control group(s), duration of follow-up from baseline (for primary outcome measure or, if not applicable, the last follow-up time point) and outcome, using standardised data extraction forms.
The highest recorded publication volume was an issue of Biuletyn Informacyjny printed in 43,000 copies; average volume of larger publication was 1,000 5,000 copies.
We recorded no publication bias with the Egger's test (p > 0.05).
For each systematic review, we recorded the publication year, the country, the topic, the participants and the primary outcomes.
Authors should be consistent in their use of terms, such as whether they are reporting on counts of citations, records, publications, or studies.
Calls may be recorded for subsequent publication as a book of hilarious and embarrassing medical anecdotes.
For each study, we recorded year of publication, study design, and country of infection.
