背景：新闻媒体经常被批评为对薄弱科学的夸大报道。新闻稿，许多记者的信息来源，可能是这些夸张的来源。目的：从学术医疗中心的研究新闻稿的特点。设计：内容分析。设置：新闻稿从10个医疗中心在每一个极端的美国。S.《新闻与世界报道》对医学研究的排名。衡量标准：新闻稿质量。结果：学术医学中心平均每年发布49篇新闻稿。在200个随机选择的详细分析的版本中，87个（44%）促进了动物或实验室研究，其中64个（74%）明确声称与人类健康有关。在95篇关于初级人类研究的新闻稿中，22篇（23%）省略了研究规模，32篇（34%）未能量化结果。在所有113篇关于人类研究的新闻稿中，很少有（17%）宣传设计最强的研究（随机试验或荟萃分析）。40%的人报告了最有限的人类研究--那些不受控制的干预措施、小样本（
Background: The news media are often criticized for exaggerated coverage of weak science. Press releases, a source of information for many journalists, might be a source of those exaggerations.Objective: To characterize research press releases from academic medical centers.Design: Content analysis.Setting: Press releases from 10 medical centers at each extreme of U. S. News & World Report's rankings for medical research.Measurements: Press release quality.Results: Academic medical centers issued a mean of 49 press releases annually. Among 200 randomly selected releases analyzed in detail, 87 (44%) promoted animal or laboratory research, of which 64 (74%) explicitly claimed relevance to human health. Among 95 releases about primary human research, 22 (23%) omitted study size and 32 (34%) failed to quantify results. Among all 113 releases about human research, few (17%) promoted studies with the strongest designs (randomized trials or meta-analyses). Forty percent reported on the most limited human studies-those with uncontrolled interventions, small samples (
