[BDSP. Notice produite par INIST-CNRS R0x59DPU. Diffusion soumise à autorisation]. Context The ability to identify scientific journals that publish high-quality research would help clinicians, scientists, and health-policy analysts to select the most up-to-date medical literature to review. Methods To assess whether journal characteristics of (1) peer-review status, (2) citation rate, (3) impact factor, (4) circulation, (5) manuscript acceptance rate, (6) MEDLINE indexing, and (7) Brandon/Hill Library List indexing are predictors of methodological quality of research articles, we conducted a cross-sectional study of 243 original research articles involving human subjects published in general internal medical journals. Results The mean (SD) quality score of the 243 articles was 1.37 (0.22). All journals reported a peer-review process and were indexed on MEDLINE. In models that controlled for article type (randomized controlled trial [RCT] or non-RCT), journal citation rate was the most statistically significant predictor (0.051 increase per doubling ; 95% confidence interval [Cl], 0.037-0.065 ; P<. in separate analyses by article type acceptance rate was the strongest predictor for rct quality per doubling cl to p while journal citation most predictive factor non-rct conclusions high rates impact factors and circulation low manuscript indexing on brandon library list appear be of higher methodological scores articles.>
