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 [CI], 0.037-0.065; P
