abstract = {Objective: The aim of this contribution is to determine what variables influence the position, by quartiles of the
impact factor, as a quality indicator of a journal in the field of Dentistry.
Methods: To this end, 24 journals included in Journal Citation Reports, 6 pertaining to each quartile were selected
by a stratified sampling and then an ordinal regression model was estimated stepwise considering the journal
impact factor quartile as response variable.
Results: The estimation procedure concluded that the average number of papers published yearly by a journal and
the percentage of systematic reviews are the most significant variables to be considered, along with the factor
representing the journal's degree of adherence to recommendations by the International Committee of Medical
Journal Editors.
Conclusions/Clinical significance: Systematic reviews have significant effect on the Journal Impact Factor position
of a journal as well as adherence to ICMJE recommendations, while papers publishing clinical trials bear no
influence on this factor. Greater yearly average of published papers in a journal means a higher impact factor.},
