A computerized search of 276 randomly selected cardiology abstracts published in conjunction with three national meetings revealed that 137 abstracts (49.6 per cent) led to full-length articles in peer-reviewed journals within a period of 37 to 43 months. The median interval between publication of the abstract and of the article was 14 months. ⋯ During the observation period, each abstract was cited a mean of 1.6 times in a journal reference list; the number of citations was not significantly higher for abstracts that led to articles than for abstracts that did not. These findings emphasize the preliminary nature of abstracts and suggest restraint in their citation as references.
