OBJECTIVE: The purpose of this study was to index the contents of the pre-MEDLINE American Journal of Roentgenology into a database that could then be accessed over the World Wide Web. CONCLUSION: The database is composed of more than 8,000 citations from the years 1914 (volume 1) to 1965 (volume 95). Using a Web browser, a user can search the database by year, volume, title word, page, or author. Results are returned sorted by year and page number in a bibliographic format. The database is accessed approximately 200 times per month.
BACKGROUND: The Digestive Diseases Week (DDW) is the major meeting for presentation of research in gastroenterology. The acceptance of an abstract for presentation at this meeting is the most important determinant of subsequent full publication. We wished to examine the determinants of abstract acceptance for this meeting. METHODS: A cross-sectional study was performed, based on abstracts submitted to the DDW. All 17,205 abstracts submitted from 1992 to 1995 were reviewed for acceptance, country of origin and research type (controlled clinical trials (CCT), other clinical research (OCR), basic science (BSS)). A random sub-sample (n = 1,000) was further evaluated for formal abstract quality, statistical significance of study results and sample size. RESULTS: 326 CCT, 455 OCR and 219 BSS abstracts were evaluated in detail. Abstracts from N/W Europe (OR 0.4, 95% CI 0.3-0.6), S/E Europe (OR 0.4, 95% CI 0.2-0.6) and non-Western countries (OR 0.3, 95% CI 0.2-0.5) were less likely to be accepted than North-American contributions when controlling for research type. In addition, the OR for the acceptance for studies with negative results as compared to those with positive results was 0.4 (95% CI 0.3-0.7). A high abstract quality score was also weakly associated with acceptance rates (OR 1.4, 95% CI 1.0-2.0). CONCLUSIONS: North-American contributions and reports with statistically positive results have higher acceptance rates at the AGA. Formal abstract quality was also predictive for acceptance.
