Also, the composition of the top groups and the median rank change show that both Handelsblatt personal rankings react more sensitively to these systematic modifications of journal weights than to the journal weight variations described before.

(Their titles were quaintly Victorian: The Entomologist's Weekly Intelligencer; Entomologist's Gazette; The Entomologist's Record and Journal of Variation).
If every author who did not have a conflict of interest submitted a statement to a journal declaring no interests, our data suggest that variations in journal policies on this point could account for up to 64% (840/1317) of the inconsistencies we observed (see Table 3).
Together, these findings suggest that there are important variations among journals in the handling of information about research support and financial interests.
Secondly, our approach also differs with respect to variations in journal weights.
Firstly, we not only investigate the impact of variations in journal weights but also in other internal parameters that have not been examined before such the way scores are split among co-authors and the weighting of different types of journal publications.
However, there may be variation among journals with respect to the time taken to be included in PubMed.
In addition, for journals' IFs there is variation among subject areas; basic science journals tend to have higher IFs than journals in specialised or applied areas.
This averages hides the fact that there is considerable variation between journals; thus, around 3.5% of articles in the two journals of national medical associations of the UK (BMJ) and USA (JAMA) were from the RoW as compared to 12% in the Lancet articles (Table 1).
