Abstract
BACKGROUND: The quality of biomedical reporting is guided by statements of several organizations. Although not all journals adhere to these guidelines, those that do demonstrate "editorial leadership" in their author community. To investigate a possible relationship between editorial leadership and journal quality, research journals from two European countries, one Anglophone and one non-Anglophone, were studied and compared. Quality was measured on a panel of bibliometric parameters while editorial leadership was evaluated from journals' instructions to authors. METHODOLOGY/PRINCIPALEntities:

Independent analyses were run for the criteria variables SCImago journal rank and SCImago cites/doc (available for 141 of the journals) and impact factor (75 journals).
a All aspects but adherence to animal research laws were considered. b Multiple correlation coefficient for all predictors included in the model; coefficients for all models were statistically significant (p<0.0001). c Percentage of variance explained by inclusion of the new predictor in the model. d Language not entered into the model because the IF journal set has only one bilingual journal and no journals in Italian.
