Comparison of number of citations to full original articles versus brief reports

Most biomedical journals accept original research articles in the form of “brief reports”. We compared the citations to full papers versus brief reports in a sample of journals on Infectious Diseases, Clinical Microbiology, and Antimicrobial Agents. Brief reports were cited less often than full-size articles [regression coefficient: 10.94 (95 % CI: 5.19, 16.69)] even after adjustment for the journal’s impact factor. Our findings may influence decisions of editors and authors regarding brief reports.
